I advise you start socialising again. If you meet another woman all good and well.
More importantly, you need to get your ex out of your head asap. If not, you'll end up going day to day thinking of her, and /or having an unhealthy attitude towards women. Causing problems in future relationships. Never ever drone on about her with other women. As I said, get her out of your head asap.
* You will never trust her again, so no matter what happens n the future, move on.
