Retroactive Jealousy

[InbetweenDreams]

Well @Justaguy said it better than I...

With regards to your previous partner, what he did was pretty despicable. Trying to make you feel worthless and guilty about things that you did before you were with him is just toxic. As for your fears that you will end up repeating his actions in your current relationship: the fact that you are on this forum asking for advice and trying to improve tells me that you are nothing like your ex and that you have nothing to worry about in that regard.

^^^^ THIS!
