It's a tough place to be in, especially depending on your ability to go out and meet new people. I would suggest putting yourself in some situations where you are around other people, not necessarily indulging in risky behaviors but associating with others. Talking to family members can also help, just everyday conversations are a good start.

I don't think it's a good idea to rekindle any sort of relationship with your ex if the relationship is of no good, you will save yourself a lot of trouble and harm by staying away ! Even being on here and socializing with users can be effective !
