Oh no no no!
As a human being you are worth so much more than that! My ex and I are most likely never getting back together, and that hurts me alot since its pretty much my fault we fell apart in the first place.
I would give just about anything to reconcile, but we both know it would be a very strained and difficult relationship.
We discussed getting back together for our daughter, but also how it would affect her if we failed and split up again.
And we also discussed the open marriage thing...together but separate...I know people do it but for the life of me I don't know how.
I understand abiut not wanting to be alone..oh I do! But don't give in to a relationship set up that is just patently unfair to you. He needs to want to heal and restore the marriage you have or it won't work. Believe me when I say I would do anything to fix my situation, but the hardest thing I have had to do is accept that it may be too late for us.
I hope this post helps you out!
