Before he preached about "strong feelings" and "love down the line" is crazy manipulative all by itself. Sorry I may have painted him in the wrong light: Yes the age gap can be OK, but in your case, this guy is manipulating you. I didn't actually like that very much. Being a player or an immature commitment-phobe with stunted views on intimate relationships does not make this guy a "Bad Person. Also deep down he probably really is the one who has an issue with the age difference, that's why he rather let it stay unobtainable and not turn into reality.
Don't date a Peter Pan-type with commitment issues.
Undressed: What’s the Deal With the Age Gap in Relationships?
I'm a 34 year old myself, and I tend to date women years younger than myself - in my experience, I'm had the best relationships from that age bracket. You're not mature enough to realize what a healthy relationship looks like, but yeah, this is definitely not it. It will only result in you feeling bad about yourself, especially when it's your first experience of sex. Block this guy's access to you online, phone, etc and RUN. You already know you don't want a life with him. I think there's a part of you that wants to help him and persuade him that you'll never believe that, and prove to him that he's a good guy.
