Why does my ex dating someone so different make me feel replaceable?

Just saw a photo of him by the Caribbean Beach with his beautiful Mexican-Haitian girlfriend.

She’s pretty. But I feel bad, because all these men seem to move on to someone totally different than me after we break up.

My first boyfriend and I broke up and he dated a very pretty East Asian girl after me, this second guy and I, he went for a totally different type from mine.

Makes me feel like I was never their type and that there’s something wrong with me.
