Trials and Tribulations

A wise person once said that you have to let something go before it can be missed. My wife and I are heading into a trial separation, and I think I need to let her go...again. You see, the first time I never really did let go. I pushed myself back into the mix, and it was wrong.
I needed that small separation to be with my own thoughts and repair those parts of me that were bleeding wounds covered with bandaids. I never really gave myself a chance to heal, instead focusing on the problem at hand. It didn't help in the long run, minute details caught up with the present from the past, and here I am again with the same wounds, but deeper and infected. I take things out on people I shouldn't, and treat people with no respect.
I snubbed someone today, and I shouldn't have. It was rude, callous, and a little uncomfortable for others, but I felt I needed to do it. Maybe it wasn't the proper thing to do, but there are points I haven't been treated as an equal by this person in the past, and I feel I am always on a short fuse lately. I guess I could have been a bit nicer, especially since they were attempting to be nice to me, but I also was taught not to talk behind other people's backs, and to treat your elders with respect.
I never get this from this person in particular, and I think they misconstrued my introvert personality as a sign that I don't care about anything. This could be farther from the truth, I am selfish, I love my wife and son, and I work hard to ensure that they can be happy. I'm not saying my wife is, obviously, since we are having so many problems.
Maybe I feel the need to be nasty to this person is because my wife has been spending most of her free time talking to her, and going out and having fun while I sit at home and wait? Or it could be some previous comments made concerning my family or myself that make me feel this way? It could be, that I have heard things said when I wasn't supposed to concerning how I am as a person.
Any one of these could be true, but in all honesty it is all of the above. I don't really care whether they understand, and maybe I do deep down. Maybe I am a bit jealous, as that is time I would like with my wife, or to have someone I could go hang out with.
I guess I need to make some friends around the area, since that is a part of it. When we moved out of our old apartment, I had friends that I would hang out with on occasions. Now, I am a homebody, and a grump half the time.
I'm attempting to overcome that, good vibrations and all, happy days with my son smiling his head off at me make my day for sure!
