It took me a year to heal with therapy.

I guess it is an individual thing. The longer the marriage/relationship was and the more deceit involved....the longer the healing takes (probably).

It took me about a year before I wanted to date again. He left in October last year but emotionally he was a gone a lot longer than that. He was planning to leave me for 18 months and was not paying the mortgage (and I didn't know) so not only was he gone but the house went into forclosure. My heartbreak was debilitating. The first four months I withdrew from everyone and only went to work and home. Then I stopped going to work. I just stopped going, didn't resign or get fired. Didn't leave the house for weeks except to buy vodka or cigarettes. February a friend tried reaching out and when she realized how bad I was getting she called my brother and he came to get everything out of the house and we were able to shortsell it. I didn't get anything close to it's value as there were 2 mortgages but even a few K was better than no K's. I flew to FL in March and I stayed with my brother and his family four months, traveled a lot (following Matisyahu across the country). I was feeling better but didn't want to date until I got a job and apartment. How appealing would I be telling people I lived with my brother and don't work...lol. I got the job in July, moved out end of August, started dating and now seeing someone regularly. Wow - I just told you my life story....

One year. It took me a year to recover from heartbreak.

It takes as long as it takes. Everyone is different.
If you feel like you cannot be optimistic, or trust a potential partner, DON'T.
If you try to force it, it'll blow up on you.

Just take your time.
A broken heart, and broken trust, take time to get over.
Don't rush it.

Good luck.

Wounds go deep,fear(s) of repeating the failure(s),limit commitment. it seems to be only two choices;
