Should I have broken up with her?

I am so confused right now. I honestly can't believe I am questioning whether I made a sound decision or not.

I had a girlfriend who is very successful in her industry and has moved up, work is important to her. I have a skilled labor occupation which is a good job also, but I work to live. I am 25 and she is 33 so I guess there was a social stigma there. She also stated to me that she never wanted to get married and was not physically capable of having children which I felt iffy about but I don't know if I want to have children in the current state of the world either.Work was a big part of her life and sometimes her "boss" nature would come home with her. She liked to drink and I thought of her friends as snobby. No one was necessarily bad to me though, I just hated the ideals of her co workers and friends and the way they acted sometimes.

I wanted to be active during time off and explore because I am not from the place where we live. She wanted to cover some work tasks on her phone or laptop and sit home and watch television. At times I felt I wasn't respected which would lead to myself getting very angry with her. But no matter how angry I got she could get over any problem that arose because she loved me. And I loved her cute mannerisms and she did many kind things that no one else had done for me before and I do not think many would in the future. She was sincere and very nice to everyone (maybe sometimes too nice) just as much as she could be a snappy "little boss".

Sometimes she seemed a little jealous and controlling. But not terribly. She was very share-oriented with her social media while I was not as big into sharing. She introduced me to her parents after her last boyfriend had assaulted her (which left her family protective and concerned). Ultimately the relationship ended because she had lied to me about going to the bar (where she would get extremely drunk with her friends) and I had to end it after I felt I had been disrespected far too much. Previous in the relationship I had found messages with other guys in her phone. I drank a lot with her and I no longer drink. This all sounds negative but there was tons of positives (made me a cake on my birthday, always tried to make me happy, would come see me 45 minutes away from her home at my place, supportive, loving) And apparently she has pumped the breaks on her drinking and partying from what she said last time we talked. We have been broken up 3 or 4 months. She said she thinks about me every day and hopes I am doing well and she thinks I made a sound decision because her actions do affect others. She says her friends try to help her get over it but she is sulking.

I just don't see myself having the kind of support I had from her but there were problems that existed. I need help I just can't decide if I made the right choice or not. I can't tell if I am just lonely or not. I remember the relationship problems (her being snappy or rude or sensitive, drinking, her work consuming/stressing her out,etc) and cringe when I think of them. I just cannot tell if I truly miss her or if I am lonely. She truly was very kind to me. I think my emotions just started to boil up as my own work stressed me out, and I am not sure where I want to go or where I want to be in life. And the stresses of the relationship got to me, but it has not been as great as I thought it would be after I ended it. I know I hurt her when I ended it. I am scared of getting back with her and facing problems again but she said she has changed her habits. I just haven't seen my life improve the way I thought it would and I even see myself becoming so much more of a homebody as of late. We would travel 45 minutes to stay with one another which threw off my fitness and routine. My finances have improved since breaking up with her as I am almost out of debt.

Please help me. I don't even recognize my own feelings.
