Don’t know what to do

my boyfriend broke up with me over text, he didn’t give me a reason just broke up and acted cold and ignorant. Later on that day I went out drinking, I called him and texted him telling him that i loved him and the answer I got was “stop I want to sleep, please don’t call or text”. I tried for 2 days to get an explanation and then i gave up until i got in contact with his best friend, he told me that he broke up because he felt it was to much, to much stress, to much arguing and that he wanted to spend more time with his friends. I totally understand that because we are basically all up on each other and i basically live with him. But with just a litte bit of communication it all would be fixed. So why leave me like that? Was i not worth it? I ended up seeing him yesterday, he drove to my house and we went outside, we talked and I cried he told me he was sorry and regret what he has done. Later on he told me that he did something stupid. My heart started racing.. he told me he had added a bunch of girls when he was out drinking.. i just got numb, he told me that it was only snaps and just like where you’re from and blablabla. we drove to his house, i wanted to cry when I stepped into his room i missed being there i really do, we talked and he said he will always love me but he feel we can’t just get back together now after breaking up publicly. I really miss him. I don’t know if I should wait or move on it’s too complicated, we were supposed to look after my dog in 3 days and he still wants to do it. If you guys want more information just ask.
