<human>: Give me the gist of the text in a nutshell

I was engaged to a wonderful man, also 26-years-old, for a year. We were living together, things were great, but I always had a nagging feeling that something was missing. I don't know if it's because NONE of my other friends are even close to the marriage stage in their lives, but the overwhelming feeling that our relationship didn't have "spark" anymore was eating away at me. 
I broke up with him and moved out. Within a few weeks I was very casually dating an older man I met at work. We've taken things incredibly slowly due to my situation and see each other maybe once or twice per week. Most of my friends tell me, "You're crazy but we still love you." However, my parents are taking a different route. I've always been incredibly close with them and have never done anything they disapprove of. It is very clear they disapprove of this. My mother has resorted to immature tactics, telling me I'm an embarrassment to the family, looking up the new guy on the Internet and then making snarky comments, asking me how "grandpa" is doing, etc. My father hasn't said a word to me at all.
Now, I am stubborn. I want to see where things go with this person because I feel a spark I haven't felt before. Yet every time I talk with my mother, I feel like I should just end this new relationship in order to keep the relationship with my parents. 

Am I crazy? Or are my parents crazy?
<bot>: Broke off engagement, got into new relationship with man 15 years older. Parents freaking out and trying to convince me not to do it.
