<human>: My SO and I had been dating for just over 3 years. When we broke up I was really upset but we both needed it at that point in our lives, a break was good. 

Soon after she went out one night and started dating an acquaintance of ours. She was completely honest and told me. This was maybe a month after we broke up. At that point I was over it and said it was okay, I still love her and just want her to happy. 

The whole time I was still in contact with my ex we work in the same building and have the same friends. Then maybe a month into my SOs new relationship they broke up. 

After a while we started getting playful again and I realised I still had feelings for her. Sounds stupid now ofc the feelings were still there but I thought I was over her. We spoke and decided to get back together. 

I don't feel the way I felt before the breakup and for me, I feel like what we have now is a weird just casual even though we are exclusive. I don't know if this feeling will go away and right now if I'm just scared of getting hurt or if I have really moved on and was just reminiscing on the past when we got together again.

When we hang out it's still great. She is an amazing, beautiful woman and in bed it's still amazing! So I'm not sure why I feel this way and if I'm being a jerk to her by not ending it or telling her.

Give me the gist of the text in a nutshell
<bot>: Broke up with SO. Get back together 2 months later. It doesn't feel the same even though nothing has changed in our relationship, hanging out still great, sex is still great. Don't know what to make of it.
