Is it finally time to let things go?! 😔

I need some advice on what to do, basically I’ve been in a 5 month relationship, turning 6 on the 10th, and he has never come to mine to meet my parents, I have to make the effort to always go to his, and his excuse when my dad can’t take me.. ‘my dad always comes and picks you up, why can’t your dad do it?’ I explain the reason why (we live about 30 minutes away, and it’s every weekend he expects me to go to his). And what winds me up is that, he can happily take 2 busses to his friends house to get high n drink? It’s not just that, i feel really confused about how I feel towards him, some days i love him, and others I don’t. We are both to blame in the relationship because we don’t really put much effort in, but some days he doesn’t speak to me for about a week, and he’s always busy on his Xbox. I have never had one of them ‘appreciation posts’ or anything like that, not even for anniversary’s or because he feels like it. Oh, and another thing, he couldn’t even come and spend some time with me on my 18th birthday because he had ‘no way of getting here’ but still expects me to go to his?. We argue pretty much all the time. And when I think about leaving him, I feel abit sick with worry because I know he’ll go for other girls. He rarely shows me love about my body, and he doesn’t get my anxiety, he just thinks it’s ‘stupid’. I don’t want to seem like a psycho girlfriend because I do allow him to spend time with his mates, but I feel like I’m hardly recognised by him anymore😔 Is it finally time to let him go?
