I'm at the end of my wits, I honestly don't think I can handle this anymore.
I've been there before.  A relationship is all about you and your bf, you don't need to handle the situation by yourself.
Speaking of which I recently realized that my boyfriend is an attention seeker.
It's normal to have ups and downs in every relationship. You don't need to get discouraged. Try to solve the problems by talking to your bf.
Sometimes I think my boyfriend is too dependent on me though and it makes me want to leave the relationship.
I do understand how this can be frustrating and that it may make you feel like leaving but if you care about your boyfriend you should try talking to him first.  You may be able to work things out without needing to leave.
