boy troubles

sooo basically, went to a party on the weekend and i hooked up with one of my closest guy friends that i never thought i would get with( as we’ve had previous things that didn’t work out) but i really wished we would. anyways we made out and it just felt like something was there and i’m a very anxious person but somehow felt super comfortable with him. he has said that he hasn’t regretted it as he was drunk but he doesn’t want people knowing that it happened but wants it to happen again, but he’s been a bit weird over text lately and i feel like he really regrets it and he said that he just doesn’t know how he feels about it. i’m super confused on whether to try n pursue that possible ‘ thing’ or too just leave it up to him and if he doesn’t want it then forget it, i really hope it does work but idk, any advice or ideas to help would be highly appreciated, thankuuu💓💓
