How do u think he feels about me?

Yeah, it does sound like he is becoming more serious about you, but... it could all end and become just a back-street-affair if you cheapen the r/s by having with him before marriage. Don't get into heavy-making out stuff. Keep things light and easy, free and breezy. Be sure your behavior continues to cause him to hold you in high esteem, you want to remain worthy of his respect.
