<human>: Can you provide a brief rundown of the text in within 3 sentences?

Now ex-girlfriend and I dated for 2.5 years or close to it. We've been through a lot together. When it was great it was great but when it was bad it was bad, and we had serious clash of personalities and choice of lifestyles. I love her undoubtedly, and I'm an extremely loyal partner and friend. 

But I can't love her like she wants to be loved at 33, I can love her the best I can for being 25 I feel guilty I couldn't give the same reciprocity and let her in closer. I want to keep things cool. And because of our weird age difference and the gender distribution of the relationship, I can make it happen. But, I'm just very unhappy and upset at the moment and I don't know why considering I was extremely unhappy in the relationship the last year, but we decided to rough it out over the holiday.
<bot>: Broke up with ex of 2.5 years was miserable the last year in the relationship but just as sad now that we split.
