I'm going to kick my pregnant ex gf out of my apt
I do not think that that is very kind to do
What do you mean with that?
I see that you aren't dating your girlfriend anymore, so there is no reason for you to let her continue to stay in your apartment. Give her a deadline and tell her that you expect her to be moved out by that date.
You don't need to make a big deal about it.
I get that that relationship is over. I think that you should give her a deadline so that she knows she has to find somewhere at a certain point. It is fine to ask her to leave as long as she has a backup plan.
