complicated feelings

My 3-year relationship ended a few days ago. It's actually a very difficult process for me. But I cannot reflect this to my surroundings. I want to cry, I can't cry. Because I'm a man, I'm judged even if I don't cry.I am judged for talking about relationship issues. Unfortunately, I live in an environment that always judges rather than understands... Actually, I'm used to it. I can fight alone.But still, sometimes I wish I could find someone who could listen without judgment to sort out the confusion in my mind. Real problem was that I could not draw my own boundaries and was very self-sacrificing.When I tried to set my own boundaries and say something I was upset or uncomfortable with, my feelings were often disregarded and I was accused of being touchy and arrogant.I really wanted to be understood and for my feelings to be taken into account, but unfortunately, my relationship with my girlfriend is not getting better anymore because I could not draw this limit in the beginning.In fact, my last girlfriend broke up with me because I said something I wasn't comfortable with.He told me that I was unsympathetic, selfish and egotistical. All I did was properly say something I was uncomfortable with. I didn't use rude or forward words. He reacted greatly and left that night. I don't know how to feel after this. These events have happened many times in different ways. We broke up several times. Unfortunately, I have no hope anymore. I have no faith left...
