Well, you're only hurting yourself - and any child you may have from all this.
you sound like my sister. she did the same thing to the guy she was with and it made him hate her. so then she did even meaner things to him , like she gave another guy head then went and kissed the guy she was trying to get. he eventually wised p to it all and now ew are together, any question read my post in sex I STOLE MY CRUSH .....FROM MY SISTER. but he may just need time and love not just sex.
You need some serious mental help so go see a therapist before you bring another screwed up kid into this already overcrowded world.
Go and see a shrink as soon as possible.
