I feel alone...

I feel like my boyfriend and I are drifting...

We’ve known each other for two years, became roommates last semester and confessed to each other our feelings after making out drunk. We’ve been dating over four months, still live together. Lately he’s been different. He doesn’t flirt with me anymore like he used to, he doesn’t touch me, we haven’t had sex for maybe like a week (we usually have sex almost every day). He’s been talking back in a jokingly rude way, if that makes sense. After he talks back he’ll like make a little giggle and say “I love you babe” like he’s just kidding about the way he’s talking to me. At first that was like ha ha okay funny whatever I love you too. But he’s been like this for a couple days now, it’s getting repetitive and I honestly don’t remember the last time he lovingly looked me in the eyes and said something kind. I haven’t been feeling very confident lately, he hasn’t complimented me recently. When I have something to tell him, he doesn’t really care he just brushes it off. He picks on me and teases me, but when I do the same to him, he gets butthurt and plays the victim. He spends a lot of time on his phone. He says he loves me but I just don’t feel the love. Lately I’ve been giving him some space because of his recent behaviors, assuming that maybe he’s getting tired of me, since we live together and spend each hour of the day together. I’m going home this weekend so I’m hoping that maybe he’ll miss me?????? I’m crying while writing this out because I know I should talk to him about this but I don’t want to tell him how I think I should be treated, you know? He should want to treat me nicely on his own, not because I told him to... I don’t really know what to do. I love him, and I feel like I’ve been showing him love, I just don’t think I’m getting that love reciprocated. I don’t really have anyone to talk to about this, I’ve been keeping this locked up inside. I don’t have many friends and my best friend has new friends and she hasn’t been very nice lately when I try to talk to her and rant. Some advice would help, or just some encouragement.
