I avoid talking about recently past relationships and so do most women. Relationships like the divorce from a few years ago and it is game on.
Yeah that line sucks. Talking about particular relationships sucks. It sucks on dates, it sucks with FBs, with mltrs and with GFs. Nothing good ever comes out of it.
Talking about relationships as a general subject, can be ok.
"I'm the kind of guy you don't want to bring home to mom. Cuz I'd fuck your mom."
"I don't have a dirty mind, I have a sexy imagination"
really? I haven't found talking about past relationships to be detrimental.
I think it's great conversation topics and helps you see where the person is coming from. Making conversation topics off the table reeks of outcome dependence too don't cha think?
I've even verbalized that I had oneitis with a girl I was seeing and i still had her an MLTR/OLTR for 2-3 years. As long as that needy behavior isn't done onto her I think it's good to go.
Rather than having no-no's perhaps there's better conversational topics to stick to tho. One of my mistakes is i go on long rants and I don't bother to look at the girls expressions and some of the stuff I'm interested in they might not be interested in LOL.
I think I sorta get away with it tho cause I talk about my passions. Basically anything that you really like, interested in, think about a lot is a good conversation topic I think.
