Overreacting???

so for the past couple days my bf has been super distant. yesterday was valentine’s day and we got in a fight because he wants to have sex with me and “ it’s been 6 months already.” anyways he had a little tantrum and we didn’t talk for the next about 6-8 hours. when he did text me it would take him 3 hours to reply. he didn’t even say happy valentine’s day to me yesterday or today which made me sad but that’s probably just my problem. so i spent v day alone eating a bunch of chocolate watching titanic and crying. so today i woke up at like 11 and he still didn’t open my snap that i sent the night before 10 hours ago. he replied to me at 1 pm and all he said was that he’d been ice fishing with his friends the past few hours. he didn’t text me back until about 5 and then he asked what was wrong and all i said was nothing. about a min later he texts “ are you sure “ so i said yeah. here it is at like 6:30 and he just now responds. idk if i’m just being stupid and ignorant or idk i just need some advice because i can’t ask my friends because they don’t like him and they don’t really care about my relationship with him. so am i just overreacting? like is this just PMS or smth? like idk

*note: we have a kinda long distance relationship 4-5 hours away
