I need some dating advice

I’ve been dating this guy for 3 months now. Just dating. He’s not my boyfriend but we’ve discussed that.

He’s a great guy, independent, career driven, nice, Attractive, His parents are great to me & I really like him.

I feel like I’m getting antsy. I don’t want to be used or just a good time. Im 28 I want a boyfriend who will be my husband & help me start a family.

I’ve brought up us being more than just dating a couple times already. He hasn’t told me specifically why we haven’t taken our relationship to the next level but it’s along the lines of him wanting me to be comfortable around him & I honestly think he thinks I’m going to change for the worse I guess as soon as I become his girlfriend. I’m not hiding anything. I’m always genuinely myself.

Ive been single for more than a year and before that I was in a 4+ year relationship. I’ve dated a few guys I ended up not being interested in. I don’t know what’s normal...I’m not sure what to do...I like him but has it been too long to be just dating?
