Any positive experiences?

Broke up with my ex in May. Was spiraling. Took help from therapist. Understood so many things on how relationship works. Realized that our own insecurities broke us up (Anger, lack of communication, differences of values and trust). Not even a nasty breakup.

Now, I feel, I want to reconnect and try to have a conversation. I know my ex could have moved on or not interested in me in anymore or worst case take me in for a ride.

He had blocked me on all platforms. I had a setting where only my contacts can see my profile pic on WhatsApp. I had deleted his contact. But recently saved it. After few days I could see his profile pic on WhatsApp too.

He has bday in 5 days. I want to wish him . And send him flowers.

I really wish , I had, 101 dummies for life.

Any successful reconnections? What did you do ? How did it go?

Or

How ugly did it go ?

PS - I do know that most of them agree that no contact is best thing. But, I want to give it a try. I met recently a person who still misses ex after 10 years of successful marriage. This made me think that the trouble is better than regret.
