How long would u hook up with ur baby mama for after a breakup?

So my ex and I broke up after we had two beautiful babies, but we have never stopped fucking and we go out on dates and spend a lot of time together. He told me he will never stop fucking me, I just want to know how long would you continue to fuck ur baby mama for? I don’t ever want to stop having sex with him either. But I’m not sure we are the best in a relationship. We were together for 11 years just for background
