Brokenhearted

Well...as I type this, my gf is on her way up to pick up the rest of my 20 month old boy's stuff as well as her other boy's stuff and stuff that she has bought while in the relationship....and she will then be referred to as my ex. Yet another relationship ended because of my addiction to chatrooms and letting stuff go beyond that many times to phone sex as well as other forms. I am so ashamed and so brokenhearted right now. Will I ever recover from this deadly addiction? And yes....I said deadly because it has now killed two relationships like I said before. The first one was a 10 year marriage that dissolved...this time it was a 4 year relationship.I feel like crawling in a hole and never coming out again. I am so afraid of being alone right now...
