Sounds to me like he’s the desperate sort. He frantically calls you coincidentally during your vow/experience of silence (boundary breaking). He sends meaningful gifts to win you. He sends clichéd over the top romantic gifts to win her. He jumps from one relationship to another. He dated a married woman.

Do you not see the blessing of him being gone? You are not expendable. The Universe is saying you are INdispensable and is trying to shed what is not good for you out of your life!
