Rachel,
It’s a courageous post. Especially because you are owning up to this obsessive behavior with her. It is also very common, more common than you might think. I’ve done it and the women I work with confess to this.

I think that some level of curiosity is normal. What you are describing sounds like a great opportunity to look into self-esteem, self-worth and how you view yourself in general.

Him dating someone else might actually have been the reason he was able to get back together with you.Whatever he needed to learn in his relationship with you, and he couldn’t, he probably learned with the next girl. This is also very common too, almost needed. Don’t use her strengths to your disadvantage. She might be the total opposite of you and that means nothing. It will be a painful journey if you use your differences to hurt yourself. And if you keep looking hard enough, you WILL find reasons why she is better than you and your self-created jealousy will erode the relationship. If he was done “learning” with her and walked away, then embrace this opportunity to enjoy him and grow with him.

Wish you the best on your journey!

Love,

Banu
