My marriage is in the dumps. I think my wife is cheating..?

We have been married for only 10 months. I am 42 she is 40. Since the very beginning she has had internet conversations with other men. When I would find out she would say they are only friends. I would see some of the conversations and from thier point of view it was more than friends. The first one begged her to move in with him and he would give her the world....That one went away after I called him and told him to stop talking to my wife....then only a month later I found that she was talking to her ex boyfriend daily by text messages and phone conversations....hundereds a day....When I approached her about this one she said it was her sister and she had her boyfriends phone...which happened to be the same name as her ex...after more research I found this not to be true.....then she went away for a weekend with her "aunt" to get away from our drama...I was monitoring the cell phone use that weekend...and strangely enough the calls to her "sister" did not exist.....in fact some calls were made to the area that he ex lives in....anyway....this continued for months and months....still the same story....she left me in August of 2009 and moved in with her ex for 2 weeks as friends!!!...came back home and swore to me that she loved me......one month later she moved out again and where she went I dont know....she came back again....and nothing changed...she claimed she was not talking to him anymore....and then the next day I found text messages and emails from him inviting her to his house for Thanksgiving dinner.....she somewhat declined....but then again she had told me the night before that she had not heard from him.....so more.....she left again in December for a week....still I have no idea where she was......but again she came back.....only to deny everything.....again in February I found more text messages from another guy that she had claimed was an old family friend...I said I was going to expose him and she begged me not to becasue it would cause too many problems with his family....his text message as this " I want an all nighter with you".....her answer to this was " I dont "F" people that I dont know".....I think her answer should have been something different....I have found emails to other men that she claims to have known them for years...only to call them and find that she just met them at work.....yea right......right now i have been out of town working for the last 6 weeks.....I have talked to her about 8 times in those 6 weeks.....she will never answer the cell phone or house phone...I went home last week for a 5 day break and she was not at home....she refused to pick me up from the airport.....she came home one time to pick up some cash from me...and then came home again for about an hour to have ....then promised to come home that night...never showed up....she came back the next morning to bring me to the airport and just dropped me off....quickly...my flight was canceled and she refused to come back and pick me up.....she said she thought I was joking when she came home 8 hours later and discovered I was actually back home......it was a bad night....she did not want me there....while i was home alone I found 4 numbers on the caller ID that belonged to other men that she claimed she went to church with.....yes a new church that she would not even tell me about ....I had to find that out on my own.......she claims to be searching for god.....whatever!!!!!....I have not spoke to her for 4 days now......I did send her one email about our taxes....kept it short....and she answered me with a short answer......other than that I am trying to put some distance between us so things might settle down a bit....but it hurts not talking to the person that I love with all of my heart....she has a mive addiction to myspace....facebook...and recently had a profile on myyearbook...which has been deleted.....god I dont know what to do.....I am sure that most of the answers will be to just let her go.....I cant do that easily....I believe in marriage and the vows.....I am still supporting her financially and some say I should stop doing that as well....especially since her income is never despoisted in our joint accout....just mine....she has helped pay one bill in the last 5 months...and that for for only $50.00.......So I await the answers....so many more details....but I think I was long winded enough......
