“Before the breakup she mentioned that it’s okay for me to do stuff without her but not every single time and she was ticked that I never even said that I wish she would have been there with me.” A man, even in a relationship, should be free to do things and go places sometimes without the girlfriend! And it’s not really necessary to say you wished she had been with you! Sorry, but she sounds like a needy person. All she had to say when you returned from trips or events with family or friends etc..was I hope you had a nice time..
“Tomorrow I will leave town until Sunday and she mentioned that she would like to visit that place too, but I didn’t invite her this time.” Good, now that your split up, you don’t have to invite her anywhere and she shouldn’t expect that you would!!
“I was thinking to tell her to let’s just stop communication until she makes up her mind, and then she should contact me.” That sounds like an ultimatum and since this would be the first no contact, it would seem like you’re pressuring her too much. Just tell her you need no contact for a month or two in order to process the breakup. During this time, she might re-evaluate the situation and ask for a conversation about a possible reconciliation and what that would have to entail. But if after the no contact, she continues to talk about very casual things that have nothing to do with reuniting, then give the ultimatum.
That’s correct, she hasn’t had time to miss you..
