I (19M) and my gf (18F) are in a long distance relationship (18 months). We have known each other for 4 years. However only 2 weeks ago did I finally meet her dad (63m). We got along fine and chatted away, but a few days later we went to dinner with him and his partner, and my gf went and changed into a pretty dress right after we sat down.
When she came back her dad seemed to be staring at her chest for far longer than seems innocent. Like 20 full seconds atleast. He then proceeded to make some comment about her dress being basically underwear. (I don’t remember it exactly) The joke was well received and came off as a dad joke I guess, but the staring was just really concerning. No one else seemed to notice.
Her parents are divorced and she still lives with both of them (week on week off) and it’s just her and her dad when she is there, and I know that she can be pretty lax with what she wears around the house because she feels comfortable.
I simply worry that her dad is being a little bit creepy. I wouldn’t say I necessarily picked up on a specific vibe other than this one incident . But being long distance means I have few opportunities to identify a pattern.
For context she has 2 sisters both of whom don’t like her dad very much and are low contact, but from what I’ve been told it’s mostly about his lack of skill as a father. And my gf has never mentioned feeling uncomfortable in his presence. (But again she didn’t seem to notice his staring so…)
How would I even approach this without levying a serious accusation that is potentially unfounded? I do worry about both her safety but i don’t want to over interpret what might’ve been an awkward one off and risk causing a rift between her and her dad.
It’s been 2 weeks now and I’ve just been sitting on it.
TLDR: gfs dad was staring at her chest, she still lives with him, we are long distance and I can’t discern an ongoing pattern, how can I approach this topic gently?
