As an example of what I mean; I have an ex who was completely besotted with me for years. He proposed and was very keen on long term commitment but then after a few years he fell out of love equally quickly and just left. Not for someone else, he just didn't feel the same, left and I never heard from him again.
I have another ex who was a much slower burn and took aaaages to say he loved me. He initially even said he "wasn't ready for a relationship" and it was quite hard actually to get to the "love" stage. I broke things off nearly two years ago because he made a lot of mistakes and he's never stopped loving me and is still sad and misses me. Despite not seeing me at all.
I'm a bit confused about whether "real" love is a feeling that persists even after you don't see someone anymore, or if it's possible for it to just come and go. I'm wondering if sometimes people who deeply love you act like they don't, and vice versa.
