I see you have an edge and you share the sentiment that I have heard on several occasions. Funny thing is you and others are probably correct regarding my ex. I cannot answer for him. However, who I can answer for is me. Sex has never made a man stay but I have heard it has made a man leave. I will say I am more than just a cheap thrill and if someone wants this ride, they are going to have to do and be more than just my boyfriend.
As for marriage, I do not see it as a saving grace but what I see it as is a commit. One that is three parts and the main part being God. I do not play with God, and therefore will not play married.
