Falling in love

I recently began talking to this guy who is 5 years older than me. I know not too wild but it’s out of my comfort zone. We relate to each other on so many things and really enjoying doing the same things. We have texted for a month and in that month we’ve hung out and have made so many memories it’s pretty crazy. He has even introduced me as “his girl” to his friends and speaking about me to mine. My fear is I self sabotage everything and am scared to fall in love (again) I always doubt me as myself and doubt the interest that anyone has towards me. I do want to take things slow but with him I kinda don’t want to!!, ofc I don’t say that lol but I like the feeling with him.
