My girl once confessed to cheating on me on mulitple occasions which led to our breakup a year and some months ago, I tried but found it difficult to move on. All the while she made constant effort to get back together so we did 3 months ago but I’ve found it difficult to trust her like i used to. I’m constantly worried and insecure about what she’s up to which sickens me. I love this girl but can’t seem to let of the past.
