Sustaining from sex.

I have decided that I'm done with sex. Not because I don't like it, but because of everything I've been through. 
I was with someone for 3 years, he was my first, I felt like I have a terrible UTI but nothing would get rid of it so I was tested for other things, and BOOM, I tested positive for chlamydia. That's how I found out he cheated on me  
I'm 25 weeks pregnant, and the father of my child made it seem like we were going to work things out, we had sex, and for me it was NOT just sex. I was bonding with him, it's hard to explain, but it turns out it was just sex for him. He went into a relationship with some girl 3-4 days after we had sex, which definitely hurt me. He's known this girl for a week and a half lol and he was telling me how perfect she is, it did get me down alittle, but I know my worth, it's his loss, not mine. He also gave me chlamydia, I found out a few weeks into finding out I was pregnant. He didn't cheat, he didn't know he had it. he already had it and then we got together and then I got it. 
I'm just tired of being hurt. All sex has done is hurt me emotionally over and over again and so I decided I am done! The right person will come along and it'll all be worth the wait!
