also for more context, we have more meaningful conversations drunk rather than sober because its easy to open up about things, he is very supportive and understanding, but not always the best with words or messaging back on time, so we talk when we talk but otherwise we just don't. i know he's searching for a girlfriend and he's made out with girls during nights out with the friend group and stuff, he is thankful for being a part of the group and close with my boyfriend and me. when i overthink about my boyfriend and i, he reassures me and reminds me that it is a healthy relationship and is supportive of us. he does give me big brother protective vibes sometimes, from moments he'd show me affection by telling me he'd torture the guy who raped me before, or how he doesn't want me upset and what's to know what's wrong because i don't know the things he'd do for me. but he's also sarcastic in his humour and tells me i'm annoying and childish, and he knows i see him as a big brother and he's told me he'd never get with me when we first became friends after i told him about my previous experiences. he's given up a night with a women he really liked (even though he just met her) to take me to my favourite spot in town after a night out because i was upset, and my boyfriend wasn't there and likes bringing it up randomly. he's one of my closest friends, and he's also joining the military in another year and a half, i'm not going to be in the country next year and after the next couple months, i wouldn't see him for years on end. i don't want to ruin things, should i just pretend to be oblivious of whatever is happening and hope it doesn't escalate?
