Hey guys, I have a quick question for you all...

So there's this girl (it was complicated between us, but let's just call her my ex) and we've been apart for sometime, and by apart I mean stop communicating. However I still see her in school (not by choice). And I've noticed that when I am around her, and she knows I'm there, I try to act more happy than she is. Even if I don't feel happy I fake it.

My question is, is this a healthy attitude when dealing with exes? She has a boyfriend now and she has most certainly moved on, but this has been on my mind lately.

Any input would be appreciated :)
