Had changes with close friends girlfriends. Never could do it even though they were not married, Just something wrong about it.
Wierd thing is, My friend got my girl friend knocked up. And his girl friend stayed at my house one night. She showed up at like 1:00am and asked to stay the night. I gave up the bed and went to sleep on the couch. Just a week before I found out.
Never spoke to him again in 20 yrs.
