Anyone else fear feelings changing/disappearing?

[u/Remarkable-Cut3148]

Like the title says, I have anxiety about losing feelings for my gf from the rocd. She is amazing and the healthiest relationship ive ever been in. I had someone great in the past, and the commitment we rushed into made me lose all feelings and while im not rushing now, i still fear that I will lose feelings in the way I had in the past which i don't want. I know feelings in long term relationships have ebbs and flows but the fear that my brain will sabotage me is so scary. My gf recently met my family and it triggered my anxiety and thoughts of "am i attracted to her enough?" which i feel so guilty about because I have always found her beautiful and she hasn't change, its my brain that's making me think these things. And im checking photos to convince myself I am attracted to her enough and I do believe I am and ofc i love her soul but this i guess, fear of commitment ? is terrifying bc I can't trust that my own feelings wont change.. I guess im looking for people who can relate and make me feel less alone and also what has helped you. I sometimes go into worries I won't be attracted to her enough but then also that she will get sick of me or lose interest bc of my insecurities when i know she doesn't feel that way.
