It is absolutely your choice and you shouldn't feel forced either way.
I am very much pro-choice, and this is your choice. Discussing your options with a supportive partner, even if you disagree, is one thing. Being made to feel like you have to do as he wishes is another.
If you have any doubts whatsoever about having a termination, don't have one. Talk to someone else, anyone else, about what you want and how you feel. But don't let him push you into anything, one way or the other.
Nine weeks is not too late either. Many people don't even know they are pregnant at nine weeks, so don't let someone else's opinion on that affect you either.
Your relationship doesn't sound good though. He sounds like a bully and an emotional abuser. Talk to someone about that too.
Can you speak to your doctor about the way your partner is treating you? They should be able to signpost you to someone who can help.
But don't do anything you don't want to do. You have time to think. It's okay to use that time to work out what you want and how you can achieve it.
