I'm looking for some advice. I started seeing a man (he's 35, I'm 30) in June and we've gone out on 3 dates (we had our 3rd date last weekend). However, I see him every other week. I'm really into him. He's definitely husband material and I'm not sure how to push him (without blatantly saying it) into exclusivity mode. I'm pretty sure he's not seeing anyone else (at least right now) as he always sends me photos of things he's doing on weekends and what not (he was overseas and has family visiting hence the gaps between the dates). He did hint at wanting to go on a vacation with me, but I've played dumb on purpose. I'm afraid to go on a vacation with him because we're not boyfriend/girlfriend and I want to pass this casual dating timeframe. Also, definitely making him wait on sex because I don't want to be used and get hurt. We haven't gone past kissing.

Any suggestions on how to push this forward gently into something deeper? I'm looking for someone to marry not casually date.

Thank you for reading this and any constructive feedback in advance.
