When my first husband went through his MLC it took me almost four years to get over it. He moved out - he moved back in - then he moved out. It wasn't until he was out about three months the 2nd time that I was done. I don't remember when the pain started leaving for sure...but it did.
His first ow - well I hope I never have to see her again. The second ow became his wife. We were legally separated by then so I don't feel the anger towards her that I did the first ow. The second ow and I are on friendly terms but now that both of the kids are over 21...I haven't seen nor heard from my ex or his wife in about 3 1/2 years. And guess what - it's okay.
I was able to move forward (and on) because God was with me. You will get there too but don't expect it to be for a while yet. Take care of you. Peace will come.
