I'm going through the same thing. It's been about a week now and I'm kinda fighting with myself over it. I realized that every time I jump into a relationship I tend to get EXTREMELY sensitive and very depressed when things seem to flow perfectly (I just don't understand why!!) I don't want to push my partner aside, but that's exactly what I'm doing and I'm dying inside because I love this person. The thought of losing him makes me go nuts and I even begin to imagine things that I know will never happen, but I just can't help it. They seem to have a way of creeping into my head, all these nagative thoughts, so my response is to ignore him and become silent.
