Dating : Break up

Dating : Break up

I broke up with my girlfriend just about a month ago, and I feel guilty for the way which I treated her during the relationship.
The relationship started out amazing, I really loved her for about the first 3 months but then that is when things started going down hill.
It was Christmas and I decided that I wanted to go on holiday with her to st. Ives in Cornwall and we stayed at the tregenna hotel and thing were going okay.
But while I was on this holiday she acted differently, and she became overly bossy and controlling of what we could or couldn’t do while we were their.
After the holiday I just held onto the relationship cause I believed that it could hold some type of future. My mom told me that in relationships their are always gonna be things you don’t like about each other.
Fast forward to the start of June and she invites me to stay at a house which she was looking after for some of her family friends.
And while we were their she would constantly make sure that I was aware that she was in charge, I wanted to go and do something outside as the weather was nice and sunny, but instead I was forced to watch 4 season of her favorite TV show. (I couldn’t leave, cause I live in a different county)
After this week I started distancing myself from her as I was preparing myself for leaving the relationship, and then the following week I broke up with her by the phone, cause she kept on making every excuse possible for not meeting in person.
Should I have stayed in the relationship and made it work?
