I know lots of people, I have been out of the tower for 30 years.
The world is full of men who cant stay in a relationship because they are thinking of other women.
I think you are normal.
You have to decide what you want in life and go for it.
A relationship requires work and has benefits. It has upsides and downsides.
At 26 you are still a young man. Some of what you say I dont understand. You say "you cant stay in a relationship because you keep
thinking of other women... since you have only had 1 partner. If you cant stay in a relationship, it seems like you have had more than one
relatioships and therefore partners.
