<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello everyone.

I break up with my gf around 4 months ago (we decided it's better for both of us this way). We've been living together until last month and now she's gone.

Like 1 month ago I've asked an ex-gf to come spending Xmas here. I was more throwing a joke-invite, but she accepted and she'll come here.

The idea is that sometimes I feel kind of guilty. I have a stupid feeling (like I'm cheating). But, as I said, me and my gf broke up like 4 months ago. I keep telling to myself that this is stupid and that I have nothing to be ashamed / guilty of.

Maybe it's because we still lived under the same roof for another 3 months. And we're apart for real for like 1 month. And we're still friends - just friends, really :)...

The thing is that I keep asking myself if this is normal. To feel the way I feel, considering the situation.

I want to mention that I didn't cheat her (in person or sexting) while we were together.

Any opinions / advices?

Thanks in advance
