What are your thoughts

I am 41 years old .I been on a relationship for almost 5 years we don’t talk about moving together. We get along well but this guy has 4 kids . I been trying to conceive and I am feeling pregnant. I will like to have a baby all this time. I live alone with my 20 year old daughter. What you ladies think of these ? I been having second thoughts and now I been thinking that if I am not pregnant maybe I should give up the idea of another baby and give up on the relationship too .. see at my age I want a more serious relationship someone who would like to be a husband I feel like I am too old to be in a boyfriend and girlfriend relationship . I don’t feel stable . When I ask him about the future he only says he wants to move into a bigger apartment so his kids can visit but never mentions me in the picture. I will like to know how women my age think? Are you ladies looking for a partner who lives on his own or a husband?
