I feel like dumping my bf because he is being distant to me.
Is there any other reason you are going to dump him?
Because he makes fun of me for being clingy to his family.
If you really are being to clingy, that's bad, and you will drive people away that way. However, if the relationship isn't working, you should move on. To do otherwise will make both of you unhappy.
I've been dumped countless times because I didn't want to be clingy.
If you think you have a clingy problem it might be good to seek therapy. I think you should talk with him and be open so you can both work on your flaws. Honesty goes a long way in a relationship.
