You don’t say how long it has been since you’ve been going out. If it is a brief time, let’s say a few months, then letting the relationship grow and making sure the two of you belong together is worthwhile.
If you’ve been together for a while—perhaps more than a year or so, then you’ll want to acknowledge a few things as you deal with her past. First, is that she has chosen YOU. Child actor, famous musician, whatever—she has chosen to be with you above them. There is a reason for that and that needs to be honored. Your love was more powerful than their fame.
Secondly, her past behavior wasn’t something she wanted to continue otherwise she would have. Giving herself sexually so quickly may not have been something she felt okay about afterwards, may have been part of a time in her life when that was exciting for her to do, or may have had unwanted consequences, or fulfilled some desire. Whatever the reasons are she’s moved on and so should you.
Believing you aren’t the type of man she truly adores is on your side of the equation. Remembering she has chosen you above everyone to spend her life with is key. When your thoughts go to your unworthiness challenge them with this truth.
