Hey Towanda, relax and don't worry about it. I think this is totally normal.
My husband left the house 5 months ago. The entire year before that he was like a bump on a log. Only watched TV and movies, only wanted to eat take-out from the same 3 restaurants. Before the separation, we were seeing a psych to get him evaluated for depression. All he kept telling us was that he was a "loner" and just wanted to be alone for the rest of his life.
After he left, he spent 4 nights a week out on the town. Started contacting friends he had not seen in years, traveled, went to clubs, bars, sporting events, concerts, fairs, charity dinners, YOU NAME IT.
Yes, I was totally ticked off. These were all the things I was trying to get him to do WITH ME!!! So, I started to do the 180 as well.
A few months into the separation, while in MC, he stated that he was "lonely" and he has to "fill up his days and nights" to keep his mind off the marriage. It is all just a distraction.
However, during these months, he has found some things that he really enjoys doing. He had NO hobbies or interest before this, so this is a good thing. He needs to go out and find what makes him happy, hopefully so he can come back to the marriage and share those things.
It is not all bad.
