im in college and me and my gf just started going out. she doesnt like PDA. i dont mind because i dont like too much PDA also. We are kinda in a secret relationship. only certain people know that we are dating. but for some reason i always worry that she is losing feelings for me. she told me that she likes me and that its not going to change. i trust her and all but the thought of her losing feelings for me always pops up in my head and makes me think and makes me go all quiet and stuff around my friends and my gf. im not sure if i should worry or if im just over reacting. help? advice? youre own experiences? thanks
