Hello everyone! I'm looking for some advice on how to handle this situation with the least amount of emotional battles and torture hahaha.
For some context:
I (22f) have been working alongside my dad (52M) in his construction corporation since I was 13. Since I knew english and technology better than him, i started out helping him write up emails, estimates and invoices, while also communicating to mainly english speaking clients. Eventually as I got older I started getting more involved and taking more of a permit runner role since my dad started working with a general contractor who would provide his license for my dads jobs. As I was getting closer to graduating High School I didn't really know what I wanted to do and so my dad advised me on becoming a GC myself so we no longer needed to pay the current GC anymore and instead I can be my own boss and maintain the business myself. I followed his advice (worst mistake of my life). I graduated with an associates in Building Construction and then took a year long break to study, take and pass the 3 gc license exams. Since the results are valid for 4 years so you can get any remaining experience needed before applying for the actual license, my dad said he would find someone in that time as i was getting my Bachelor's in Construction Management that would provide me with the experience I needed for my license (the 1 year of foreman/supervisory role of a project of more than 4 floors under a gc).
Now on to the current situation:
I am about to graduate with my bachelors this December and my dad still had not found someone who would be willing to provide the experience that I needed for money (as he doesn't actually want me working under someone else that isn't him because im sure hes afraid that i may enjoy it more than working with him and so i can only concentrate on his jobs, which he isn't even having much of these days.) I've been taking advantage of this by searching for other jobs under the guise of me needing to do what I need to to get the job experience I need since he is not able to. I did a 6 month internship with a small subcontracting company and during that time it was hell at home. I'm talking about constant arguing and criticism about how it's not even a GC and it's small so I'm wasting my time there instead of helping him, and that I shouldn't have shown them my actual school schedule so that I could do less days working so I can work with him those days. Even going as far as saying that i had to choose between my time with friends, bf and him because my internship and school was already taking up all my time. I ended up leaving the internship because either way there was no growing or new learning opportunities and I have been looking at a big gc company that does huge projects that everyone wants to work for. After a long time of doing site visits and interacting with this gc company, also with the assistance of a wonderful friend who works with the wife of someone who I look up to in the company, I have done 3 rounds of interviews with them and I am 100% sure that I will be receiving an offer. Here's the hiccup. I tried to keep this as lowkey as possible so that i wouldn't get any negative vibes from my dad but one of the days of the interview he was home and i didnt want him interrupting me during it so i spilled. Immediately after this he somehow found someone who went to a company who helps you apply for your gc license after you pass the exams (they help you write up your experience and get you everything you need to apply for your license so everything goes smoothly) who said all he was missing was that 1 year of experience under a general contractor and they somehow helped him get in contact with a general contractor who he paid to give him the experience. I DON'T WANT THIS! I'm afraid if the same works out for me, i'm stuck under my dad's finger for the rest of my life and even if i do end up saving some money to leave, i would pretty much start from scratch because my team would just be his current team, and my clients would just be his clients. Not only that but I wanted to join a company to actually be guided and trained and actually have a team who has my back. Working with my dad I have had to learn everything by myself, hitting thousands of walls, through insults and disrespect because it should be expected that I already know how to do everything just because I know English and have had some construction classes. I've been saving up money to move out and take my mom with me as silently as possible so with a stable income from that big company I thought I'd also be able to save more while being more independent and being out of his grip more. He has already scheduled the appointment with the company that the guy he met said hooked him up for tomorrow. I am afraid that my fate is pretty much going to be determined if I will stay a victim for this man forever and never grow or be anyone with him holding me back.
How do I say that I still want to work under another company even though I no longer need the experience if I do get my GC license this way without him blowing up about me wanting to just work for someone else and being a slave to another company when I can concentrate on just growing on my own? Please, Any advice would be helpful.
