do i go back to no contact?

i recently broke no contact with my ex of 3 years because i heard they were trying to get with a close friend and i wanted to confront them (i realize we were already broken up but i acted out of emotions ok, and we said we’d focus on ourselves and wouldn’t find anyone else). turns out they just did it for their ego and never really thought of pursuing them.

i’ve also tried so much to convince them ive changed and if we could try again but they really don’t want to. they just want to keep things purely platonic, noting we can reassess in two years but i shouldn’t keep my hopes up. they were even saying things like “i dont think i ever really loved you. i think i just said it because you wanted me to”. and now they’re getting me to try new things like get with people, break their hearts, and find more friends (we were best friends before we got together).

but hurtful things aside, we always have the best conversations and we’ve been calling each other everyday (platonic on their behalf, platonic/romantic on mine). i feel so relieved having them back in my life and having my constant back, but at the same time i don’t feel at peace?

i guess i just would really appreciate some advice on if i should stay in contact with my ex? like i love talking to them again but in the back of my mind i can just think of all of these things they have said to me. they’ve definitely changed, and i respect that but honestly idk if i’m respecting myself by doing all of this. ahhhh please help
