Entanglement with my ex

Mani

So, me and my ex, lets name him Timmy, have reconnected. We were high school sweethearts but didnt go to the same school. We met when we were 17 and were infatuated with each other and it was healthy until at one point we couldnt see eye to eye. He felt like i didnt like having sex with him even though he didnt understand how inexperienced i was. Also his mom was not that welcoming and I had to be snuck into the house to spend time with him which influenced me being awkward during sex. Soon after, we broke up.

We both moved on and he ended up having a child with another girl. They were having issues I guess and he was dating one of my friend’s twin sister and it hurt me. He wasnt aware we knew eachother but it made me awkward between both the twins because I didnt know which bitch was fucking my ex. We reconnected again back in 2019 when he was single and he attended and supported to one of my art shows. We had good time But I went thru some chaotic events and so did he and caused us to grow apart again. We rekindled once when I got stabbed and he got into a car accident at the same time and reached out to each other to pray for one another and then separated again. I had to go to therapy after being stab by one of my coworkers and it helped me enter a better mindset to be open with him again. I asked him 3 days ago if he was single and if he had a girl friend and that i dont want to disrespect a relationship he could be in. He said he is in a relationship but it wouldnt be disrespectful. He is back in a relationship with his baby mom strictly for his son and he says he doesnt want to be with her but hes okay with being with her for his son. He said when I messaged him him and his BM were just arguing about her not wanting to have sex with him and her taking his car after hes been working for long hours to hang with her friends....

He has been calling me everyday for the last 3 days. I really like the energy but i told him i dont want to be a side chick. I want him and i dont want to share. He said he likes my energy but he doesnt want any altercations between me and his BM. What should I do I want him back and he wants me back and I want to be the woman to make him happy. I need advice and thoughts. I dont want to be judged. I never been a side chick and dont plan to.
