Hello Rafael. It's me again.
There is one issue making things more complicated, and that's the online emotional affair my girlfriend had when we were separated. It had started about 10 days before we got back together.
It is a random guy from her hometown who she doesn't even know personally who randomly started talking to her on facebook. She grew fond of him very quickly, as she was apparently needy. She later said to me she was needy and that he told her everything she wanted to hear from me, and I wasn’t there anymore to tell her. She thinks she let herself get emotionally involved with him because he lives far away (in her hometown that she seldom visits, as she works and studies where I live), so she wouldn’t really have to get real with him.
I asked her not to talk to him till she decided whether or not we’d get back together, as it could definitely be the end of us, making her drift away from me completely, as I cannot compete with someone who's partly idealized in her mind. She didn’t contact him again since.
Then we got back together. He still sends her SMS sometimes and probably facebook (that she hasn't checked in days - I don't know if she's afraid to) and he sent her a bonsai tree by mail the other day. She hasn't contacted him and feels guilty. But she also said that the breakup had 'serious consequences', meaning her apathy towards me and her feelings for this guy. I asked what she felt for him and she said "I like him... I don't really know HOW, but I do".
So, that's it. She seems confused. I don't know if she is feeling guilty or if she really likes him over me, and it's killing me, becase this seems not to be letting us move forward in rebuilding our relationship.
