I am not removing the pool table. I said she wanted me to not the same thing. I put a ping pong table on top though which is better for the kids and safer for my felt. Eventually it is just nice to have someone to share coffee with in the morning. I am 44 years old. I don't run around town. I am not giving up anything.
She is talking about it before she has even moved in. This should be a little bit of a warning sign if not a red flag. Right now it is still "your house." Once she moves in with her girls it will be
our house but in reality it will be
her house because she and her girls can 'out vote' you. She will say "if we live here then our opinion is just as important." It won't matter one bit that you own the place and lived there first. Eventually she will make you miserable until you give in and do what she wants. She is a lawyer she either argues for a living or studied how to win those arguments you will not win with her even if you are right and she is wrong.
It is nice having people around we can't all be agoraphobic hateful bastards forever. Worst case it goes horribly wrong and you wind up right back where you started.
Just because you want to maintain your own place doesn't make you hateful or agoraphobic. You can still enjoy time with her and even have coffee with her. What's stopping you from spending the night there and having coffee at her place?
Having someone move in with you is a huge step. It is an even bigger step when they bring their kids. Don't do it just because you want a coffee drinking buddy.
