Wife no longer in love with me - Part 3

[cam]

Country, I know what you're saying and believe me it has crossed my mind since this whole thing started. Now I may be naive, but I honestly don't think there is another guy involved.....she just seems so messed up to consider this. Although the girl she lives with is single and always trying to meet guys.
My w is a sweet, lovely girl who has been through so much sh!t in her life, and she is messed up. She thinks this will make her happy and she wants to start her life again.
I don't know, maybe I'm just foolish, but I see all her reasons why she feels this way about me, I see how i was over the years and hell, I wouldn't love me either! I pushed her away with my moods, my immaturity and basically being a jerk - she couldnt take anymore and was sick of trying to make me happy.
Which wasn't her role, she was not responsible for my happiness, I was and am. She felt she was always trying to do the right things by me, and now she can't give anymore.
If I find out if there is an OM, I will rip their f Ken head off! Ok, angry cam calm down!
Do you think I should hire a PI to find out once and for all??
