I am glad that you came here to vent. You needed that. You can't keep things inside all of the time and here you can get some unbias oppinions from others.
Do you think it is just all of the stress that is getting to your son? It sounds like it to me. He might be abrupt with his fiance also and maybe that is where the arguements are coming from. I know that he is working on stress issues with therapy. But sometimes that takes a while to get through and that could be what is going on right now.
I know that you are concerned about him, but maybe you should work on your issues about feeling like you are losing the family. Maybe it is just some changes going on. Families may seem to grow apart, but I don't think that they ever really do. There are too many memories going on there.
I wouldn't worry too much, it just sounds like he is under a lot of stress right now and he has to worry not to take on other peoples problems also. I think this is just a learning process all the way around. So just be patient and you will get your son back.
I hope that this helps a litlle.
