Date night

So I went on a date (first one in 5 months) with my SO last night and while we were sitting there eating he looks at me and tells me he's responsible for me. I informed him that no one is responsible for me but me. He thinks that since we've had sex and I'm carrying his child that he is still responsible for me. I told him over been on my own for 15-16 years and I've been a single mother for 13 almost 14 years so no he is not responsible for me at all. We don't live together and even if we did he still wouldn't be responsible for me. What are you ladies thoughts on this?
