I don't know wat to do 😕🤦🏻‍♀️

Me and my boyfriend have been dating for 8 months but I feel like he doesn't like me anymore and I'm thinking of breaking up with him. But the thing is, I have really low self esteem so with any relationship that I have whether it's friendship or romantic I just assume they get bored of me at some point so I'm the one that breaks contact to not get hurt. My boyfriend tells me he loves me and is really affectionate I'm the one that's not that affectionate actually but I just keep feeling unwanted and Idk what to do cus I don't want to break up with him but I feel like I have too.
