Thanks. So I have to be blunt, as a 26 year old grown man you really should not have been going after a teenager. There is not only a significant age difference, but also a significant power imbalance.

Your ex was a teen mom struggling with her mental health. This entire time, you have been a grown adult. Do you see why that is incredibly problematic?

Was her pregnancy planned?

Honestly, you can put the request in and see what happens, but I think you also need to take a lot of responsibility for all of this too. I get that you are taking care of a child mostly on your own, but you're at an age and a stage in your life where it's reasonable and easier for you to do so. She is not.
