I went through something similar following my divorce, except I didn't have male companionship to fall back on. I was desperate to find a new relationship because I was emotionally needy - which never turns out well, as any relationship formed under duress is doomed to fall apart before long. And then there was the little problem of never wanting to go anywhere or do anything unless I had a security blanket (husband/bf) by my side.

The end of a relationship is usually more traumatic for those of us with MIs because all of a sudden we're bereft of our "crutch" that we've been leaning on, and we're faced with not only heartbreak, but all of our issues we were able to brush under the rug and avoid dealing with when we had that crutch to lean on.

Have you considered therapy?
