How to Deal With Retroactive Jealousy

You cannot work on retroactive jealousy if you can't work on your relationship with yourself. It's an insecurity, feelings that you're not enough and needing to be validated. So that all comes down to self worth and self love. If you feel really good about yourself, you know that you'd be fine alone and also with your partner,. then you would be so fine knowing that they were in love in the past... You'd be happy to hold your own but only when you feel shit about yourself.
