19 f 25m wont have sex/ not interested at times?

i have been with my boyfriend since last july we first just started to fool around basically then we gaiend more interest by the end of july and were together. he did live right by me but in september he moved back home about an hour away from me. id visit weekends and we`d either stay at a hotel or his house when his parents wernt there ( i didnt want to meet them because of my age and they didnt allow us to sleep in the same room together, still dont) when i visited, we would have fun and lots of sex for that night or two, which is so different from now. the last few months whenever i go dont he never wants to, sometimes we dont even, if i am lucky we will have sex once that weekend. everyone is saying he just might not be interested or is cheating. and im thinking they are right. we have had a threesome before and it didnt bring us closer. he seems just to not be interested at all, but he says he is. i always go there weekends and i feel he doesnt even appreciate it anymore, he just legit sits there and plays video games for hours and i sit in the bed till we go to bed. i love him and it used to be so great i dont know what to do. p.s i am moving down there in august

You are out of luck. If he has lost interest in sex, that early into a relationship, even after you gave him a threesome, he's beyond hope. Sorry.

He wants you to dump him because he's a coward. The relationship has run its course and has run out of steam and passion. You could try and rekindle it or move on. Maybe he takes you for granted.

Um.. if he's had threesomes, he's probably cheating on you. Get yourself checked for STDs.

there probably something bothering him
