My boyfriend made me insecure

He had Instagram and he would follow a lot of slutty girls and like naked girls online

I confronted him about so he unfollowed all the slutty girls

But then again later after a couple months, he follows more slutty girls and he still likes naked pictures of girls

I told him how I felt, I felt like I’m not what he wanted because they look nothing like me

They have it all

The perfect body, the perfect everything

And I am unfortunately an A cup bra size and that is obviously not what he’s into

The girls who he likes on instagram have huge boobs

And I am going to get a boob job because I wanted him to like me

Then later he feels bad and deleted Instagram

I didn’t tell him to do that

But now he started doing the same thing again on Facebook

And I just can’t deal with this anymore

Should I break up with him? I’m upset because I really like him but I guess he doesn’t like me as much as I thought he did
