sally_d,
Hello...

I agree with MysticalMoon about you already knowing what you want to do...
It's very hard for many us to take care of ourselves...we put the needs/demands of others before our own.

It's all right to set boundaries on him and anyone else. It's all right to say No, and stick to it.
You are the making the decision based on your needs and your wants--not anyone else's stuff.

If you need to give yourself more time to make a decision, it's ok. Try not to let others pressure you into doing what they want; make your decision based on what is best for you.

My best wishes,
Cap
