I don't love my boyfriend anymore
What has made you fall out of love with your boyfriend?
He's got a nasty attitude and he also makes me feel awful about myself.
Abuse is never good in any relationship. You should break up with him if you are no longer in love. It's best to just move on.
Why do I have to be the one to move on?
Since you are the one that doesn't feel in love anymore you should be the one to leave. It's important to get out of bad relationships when you can.
