I need your help..... 😔

Ive been with my boyfriend for about 2 years, and I love him more than anything.. so i thought?? like, i love him a lot but his actions make me upset and frustrate me. he has always gotten man when i wouldnt sleep with him, mind you he is my first and only sexual partner.. but after we started having sex he just didnt want to stop lol and now its gotten to a point where he will wake up the day after not having sex and IGNORE ME and hes irritable all the fucking time. He doesnt care about my feelings, i could be baeling my eyes out in front of him and he would roll his eyes, sometimes he gets mad when i doing someyhing dumb and he lets me know just how "retarded" i really am. I dont get it, i dont get why he would do this all to me. i put everything in my power into makng him happy and i feel like i get jackk in return. problem is i love him🙄❤ i love his good days amd his cute giggle! i broke up with him the other day and decided we were gonna work on it but he was hateful, he told me bye forever and put me as Ex. on messenger because i put his regular name... he told me he wouldnt be like that if he got more sex. i just feel like i am missing out on the world and i think hes trying to control me to stay because he does get upset and cries but how do i know what to do? its my first relationship. 2 years is a long time when youre 18!!!
