For me it was knowing I had no desire to entertain the possibility of being with anyone else. I knew I'd love him for life and could not take the risk of losing him.
He LISTENED to me and actually paid attention to the small things, even things like saying 'please' and 'thank you' for even the smallest actions (refilling his soda). And he was/is very respectful of me as a person in general. I'd never experienced any of that before and it just blew me away. We've been together 13 years, 6 of those as a married couple. I'm 56 and he's 41. He's definitely a keeper!
He and I shared core values and he was a very sweet, kind man.
He did everything possible to make our relationship work... We are two opposite people. We clash all the time... But We always calmly work through it
He is a person of great moral and values. He's also fun loving and responsible. When I felt he was worthy of long term, I saw he was willing to make compromises for my and our sake just as I am. We both voice our opinions and talk through our issues and come to terms we are both happy and comfortable with.
He wasn't trying to change me into this and that. He accepted me 100%.........just as I am.
