I had a good relationship with my ex boyfriend that i dated for months. I feel that sometimes our relationship was toxic. After the break up happened it was very upsetting for him, i feel as if he took it way worse than i did. we remain friends, and got in an argument and haven’t talked since. The argument resulted in un adding one another which i feel is very immature. A few days ago I feel he requested to follow me and tried to add me back on several social media sites. If this is a relationship that I feel like I should maybe try and pursue again should I reach out to him another question I had was why would he add me after all the time?
