Immensely confused and frustrated...

I've been with my boyfriend for over a year now. A few months ago I woke up, and it's like ever since I just can't seem to get this baby alarm to quiet down. I'm going to 24 in December, and he just turned 27. I'm at the point in my life that I want to get married and start having my babies.

He doesn't want children what so ever, he's always saying that he doesn't want them or that he's not ready. The frustrating thing is that my ex started messaging me, telling me that he wants to marry me and have children. I have known my ex for 18 years, at one point before we broke up we were talking about marriage and children. I just don't know what I should do, especially because I am crazy in love with the man I am with right now.

I was just wondering if any of you ladies, or gentlemen that post might have any advice ?
