If they were both super busy for one another why would she still stick around? It makes for some hot crazy intense sex. If before, then I'm not impressed but if it's only for a couple of dates and she hasn't slept with any other guys, then whatever. I promise your girl will give you the best sex you ever had. The only weird things is why does she goes out of her way to tell you she dates other guys? To the addict, relationships are boring.
Yes, early, mostly from the interaction between their mothers and fathers.
What to do when "new girl" is seeing other guys?
I have very strong ideas about relationships and love. The obstacle many guys face is an unwillingness to be vulnerable. If she doesn't want a relationship, just pump and dump. Nothing wrong with her seeing other men since you guys are not exclusive. I played along with the dialogue to see where it would go.
