Is it normal my ex keeps acting nicer each time we break up?
My ex and I have dated twice, both times I initiated it and ended it. We had problems each time, but I noticed lately that she's acting more and more amicable. The first time we broke up, there were a bunch of reasons for it, but one of the big issues at the time was a lack of physical intimacy, she was extremely shy, I stole her first kiss and she was terrified to go beyond the that. After the break up we remained friends and she very quickly began acting much more intimate, and started becoming more sexual than I'd expected, (though still nothing that could result in pregnancy) Eventually we started dating again this time for more than a year.
About 2 months ago I broke up with her due to our extremely clashing personalities. She has a lot of personality quirks that dealing with finally wore me down, namely she refused to talk about any subject that didn't fit her personal interests and would get angry over almost anything, and she just didn't enjoy talking about most things. After the break up again we've remained friends and lately I've noticed her personality seems to be changing, I've been able to talk to her about more subjects, even politics for a while, and she despises politics, she used to shut down such conversations.
So I guess my question is, is it normal she seems to keep changing each time we break up, Is she trying to get back together with me, or do we just get along better as friends than as boyfriend and girlfriend?
