Photo is illustrative in nature. From open sources.

I am 27 years old. I don't have children. My boyfriend and I have been living together for a year now. For a year, we never even had a fight, everything was perfect, I trusted him very much.

A month ago I found out that he was withgirls of easy virtue. We had a very big fight, I packed my things and left him. Of course, I was very offended and I don’t understand why he did this to me.

He started to comeevery day to my work and said that he couldn’t live without me, that he had stumbled once, that he was drunk. He unexpectedly proposed to me right at work, and I agreed to marry himmarried

After this moment, two months passed, everything was perfectly fine, but my state of mistrust only worsened. I begin to take details of his calls, follow him, suspect him of everything. I love him very much, we want a child, but I really don’t know what to do? Can a person change? Or is it better to break up now?
