Boyfriend about ex.

My boyfriend once made a comment that his ex gf of 7 years made him wait 6 months to have sex.. Like he some how respected her for that.  It really got to me because after talking for 6months on the Internet when we first met in person I gave it to him.  Now I feel like he doesn't respect me and I don't really wanna have sex anymore.. I keep thinking of how he said he respected her.
