So sorry you are going thro this. I have been in this position before. I was not allowed to have an opinion and I had to make the choice partner or baby. And I was told if I choose the baby I would be raising it alone. I gave in and I choose him only for the relationship to end anyway. I wish I had been stronger and taken more time to make the decision on what I wanted instead of bring blackmailed and manipulated like I was. I have a lot of resentment and anger as a result.
It's a horrible situation to be in. Sending hugs your way xxx
