Why would a man who you thought was interested in you suddenly do this?

Mentioning other women or going out with other women. I don't know this man well, bit I kind of like him. We've communicated for a long time either through email and a texting app. We've only met 3 times (his country) and I don't know much about the dating culture there, just some. They are not like American men are with dating. I know there is not much for me to hope for being he is so far, and we have never spoken about feelings. I'm not good with showing interest, I just continue to write. He says he is shy himself. But he continues to write almost every day, and this is the 2nd time he has mentioned other women. This time, it is a "new friend". :( I am wondering if this is his way of just saying goodbye to this relationship we have.

I'm going to add a note here which may bring about some new insight. He, I think, may be very proud. I've been in his country twice, he has never been anywhere in 30 years besides his own country and in Hawaii, Malaysia. He doesn't seem to have much but a home and a car. He once said he could not afford a car like mine (it's very old). Sometimes, I wonder if he thinks that he is not on the same economic "level" as I am, or maybe that I'm well off (I'm not at all). He may not like this.

The “new friend” turned out to be, a young guy from Latvia. I feel like such a fool. He didn’t specify the gender, and I assumed it was a female when he said friend. Oh no….
