My boyfriend and I have been dating for nearby 2 years at this point. After 6 months together, we had some issues that almost lead us to breaking up due to how stressed he was due to his depression and some exams he was taking, but we talked about it and came back stronger than ever, and ever since we haven't had literally any other issues. We can openly discuss anything, we hold the same ideals, and we share a lot of hobbies and friendships. I cannot imagine anyone else being such a good fit for me or loving anyone else as much as I do now.
Currently, we're doing "long" distance, and I say "long" because we still live in the same country, but live 3 hours apart by train, which is sort of a pain, but we make do and try to see each other at least once a month. Due to this, texting and videocalling is obviously a big part of our relationship at the moment, so we are texting more or less constantly. Obviously if one of us is working, or hanging out with friends, or whatever, this slows down, which is normal.
Due to having a lot of friends in common, we also have plenty of shared group chats with said friends, which means that besides our private conversation we sometimes also talk through these group chats with some friends.
Due to this, lately I've noticed that sometimes, if I ask him a question or whatever in our private chats, he might take ages to reply (which again, is perfectly fine, I do it too when busy and I see no issues with it), but as soon as someone says something in a group chat he replies much much faster, often leaving my message unreplied even though... they're with the phone in his hand, replying to another person in that same moment.
This has happened plenty of times, to the point I'm starting to feel crazy about this because I know it shouldn't bother me at all and it is a stupid issue to have, but seeing my messages go unreplied while he's chatting away in another chat just irks me, specially the more he does it. If we could see each other every day instead of being a LDR, I wouldn't care at all about this (I think), but feeling ignored in one of our "only" ways to communicate at the moment just makes me somewhat mad. I haven't raised this issue with him or my friends yet because again, even to me it feels incredibly stupid and I don't know if this is something that should bother me or if I'm making a mountain out of a molehill.
Besides this, I haven't noticed any problems whatsoever in our relationship. Last week he introduced me to his father, and he has expressed how much he wants me to meet the rest of his family, which would be an absurd thing to do if he was losing interest or whatever, so I'm pretty clueless at the moment.
