Better half doesn’t want kids

So me & my boyfriend have been together for a year and half. I am 21, I have live all 21 years fully as I desired and I am ready to settle down he is 27 and has accomplished all of his life goals. He was married & had a family, one girl of his own which is almost 7 and two step daughters. The divorce was finalized when we were dating. We have lived together ever since we first started dating. So fast forward to last year at Christmas; we went and picked out a ring together found the place, price & a card with the salespersons information on it. My boyfriend said that he was going to purchase the ring once he received his income taxes. Time came and he went and bought a deep sea boat instead. TYPICAL guy thing to do! Not saying anything at all I just bit my lip and figured maybe he didn’t want to rush it. So I have yet to say anything about that, because how would I? Without it sounding like I’m rushing it? He has brought it up a couple times now that he doesn’t want anymore kids. HUGE deal to me! First time he mentioned it I left went back to my house and stayed there for the night. We smoothed things over the next day where he said he didn’t want anymore right now but we may could have just one later. With that in mind I was like okay and I just let it go. He claimed he’s almost 30 and is going to be too old to raise another kid.. crazy I know!! So, today on my lunch he said something about our baby animal (that we are trying to save) that he didn’t want it anymore babies and if he wanted to raise a baby he would have one. I put my 2 sense back in a made a smart remark and he said it again; that he wasn’t having anymore kids. I went on to tell him I was going to have one and that I would bet on it! He then asked what was I doing with him there just passing/wasting time? I replied yes I guess so. I love this man with everything in me and I am completely torn by this. Someone give me some words of advise or encouragement! I don’t want to do life without them and it breaks my heart considerably to even think about it. But it also breaks my heart knowing he doesn’t want another baby and that I could possible go and be without kid(s) of my own. I love his little girl as if she were my own, every time we have her I take her to do whatever she wants and she actually spends more time with me than him I would not know which direction to go with him and her but this situation just tugs at my heart. I wish I had a 5th of his selfishness 😢
