Child of Divorced Parents Both Dating People

For reference I am 26F and my parents were divorced by the time I was 7. For some reason, I hate that my parents date. I hate talking about it and hearing about it. I don’t really remember my parents ever being together other than pictures or them sitting us down to tell us they were divorcing.

Mom: just started really dating a year ago but only one man who is very nice. But I think it’s the fact that growing up when with mom it was us against the world. Now it’s not and it just feels lonely especially since sister is also now married.

Dad: cheated (reason for divorce), got married to her 7 years later and then got divorced again when I about 20. Now it seems like it’s a different girl every week and some are way too close in age to me (3-4 years apart from my sister) but also hangs out with girls around me and my sisters ages which I find absolutely disgusting.

Not sure what I am looking for whether it’s opinions or support. I might have just a more “typical” look on family, but are my feelings at all valid?
