About my boyfriend secretly going on a blind date behind my back, and even going to find a peripheral girl behind my back

I felt very angry and disappointed that we were both about to register our marriage, but he suddenly went on a blind date behind my back, which made me feel very distrustful and disrespectful.

First of all, he explained that it was because he was dating a friend, but I don't think that's a reasonable explanation. If it was really for a friend, why didn't he tell me in advance? Why didn't he discuss it with me? This kind of behavior is obviously irresponsible and disrespectful to me.

Secondly, he actually pretended to be affectionate in the last second, and turned around to find a peripheral girl to solve the physical problem, which made me feel very disgusting and unacceptable. How could he do such a thing to deceive me? This kind of behavior is not only disrespectful to me, but also disrespectful to marriage and responsibility to the family.

In the end, he also swore by his family members and made all kinds of quibbles. This behavior made me feel even more disgusted and untrustworthy. Does his family know what he did, and if he really cares about me and our future, why would he do this to hurt me?

In short, this incident made me deeply realize that there is a problem with this person's character and moral quality. I can't imagine what it's like to live with someone like that for the rest of my life. I hope to be able to end this relationship as soon as possible, re-examine my values and lifestyle, and find someone who is truly trustworthy and trustworthy for life.
