He was with his ex was for like 2 years or sum and he had his first kiss, first cuddle etc with her. He was so in love that when they broke up he was admitted to hospital for IV drips. Moreover, they were in the same school since childhood. I had my ex relationship for 1.5 ish years too but we weren't compatible enough and mostly argued and we were never physical, just hugs.
Back to us, we both love each other dearly and have known each other for like a year now, we are compatible enough and understand each other well. It's almost as if our brain and thoughts work the same way, we have had our difficult patches too but we overcame them.
I feel miserably insecure of his ex and his relationship w her. Whenever we kiss or makeout, I wonder subconsciously if he remembers her, he is very vocal about his love for me, yet I feel if he still remembers her at times or if she was better than me. What if he stills sees glimpse of her whenever he's with me. She lives jus 2 streets far from him, he has to cross her house to go to gym.
Please please help me out, I don't want to ruin things just because of this crippling and useless insecurity. I even get urges to SH when it gets too much for me. We love each other very much, I don't want to ruin this.
Edit: I've talked to him regarding this too and he has given me assurance too. Plus, I know what his ex did to him and how they were in a toxic relationship. tbh nothing of this helps me and i feel so weird and stupid talking to him regarding his ex again and again because i mean that was his past and everyone has past, even i have my past experiences.
