Updated:: Help please. I’m so confused with him.

So my SO and I have been together a few years and have an amazing little boy!! He keeps saying down the road he’d love for us to get married (we already have a house) but he doesn’t want more kids due to his age. What I don’t understand is he knows I am not on birth control he knows I am a fertile myrtle but still wants to have unprotected sex and always finishes in me. Knowing I get pregnant easily I would think he’d at least want to pull out (yes I know that’s not 100% effective but it’s something)

I don’t get it?? I have brought it up to him a few times and he just says “eh oh well” and drops it. I am really confused on this whole thing like why is he not more careful if he doesn’t want more kids?? He knows I do want one more. Do you think this is his way of being like he’d be ok with it if it happens? Idk what to think 🤷🏻‍♀️🤷🏻‍♀️🤷🏻‍♀️

6/11 update

So we talked this weekend and even though we had just had a conversation about 2 weeks ago when he told me he didn’t want more kids he said he is open to the option of one more because he knows I want one more.

I started off saying that we need to start being more careful and start taking precautions when having sex because we are extremely careless if he doesn’t want more kids. He asked if I thought he should get a vasectomy I told him that is more his decision than mine as we aren’t married. I don’t think that’s something I should be deciding on. And he told me that he isn’t completely against having one more as we both have older kids from previous marriages but we want him to have someone here closer in age and a playmate. Sooo it looks like we may be having another baby 😁😁😁
