Fitting in a relationship after getting used to being alone?

So I was single for many years after a very traumatic ending to a relationship (child loss, cheating just to provide some info) . I find my self having trouble maintaining relationships now because I am just too guarded and find my self in an internal war with both wanting a relationship but also really enjoying being alone and just being able to live my life as i want.

Anyone else ever get this way? What helped you heal from this and start being able to trust again and fully enjoy relationships?
