Me [36F] with my bf [34M] 4 years, Is it unreasonable to not want his 13 year old daughter at our anniversary dinner?

Sometimes it seems like my bf tries to put his daughter (13) in between us, so to say. I have a son (16), so I understand how important the parent-child relationship is, and wanting them to get along, and not wanting to feel like you're neglecting your child for a s.o., etc

But, today is our anniversary. He wants his daughter to come with to our anniversary dinner. I get along with her well,but I think our anniversary should be about just us. (Also, I walked in on him with another girl in his bed about 5 months ago, so our relationship is strained- majorly.)

Another example I can think of is on Valentine's day, we had planned to go to dinner. But by the time I got to his house, it was already 7. I had to pick my son up from work at 9. We decided it would be too rushed to go out to dinner, and we could celebrate another night. When I asked him to come with me to pick up my son, he said he needed to spend some Valentine's day with his daughter. We would've been gone like 20 min, he didn't plan on spending this time with her since we would've been at dinner, and he was home with her for 4 hours after school before I got there. When I said that reason didn't really add up (he sometimes makes up weird excuses that don't make sense when he doesn't want to do something and I started calling him out after he cheated) he got defensive and literally yelled at me "Doesn't Kylie get a Valentine's Day, too??" I was like, what? That doesn't even make sense...

It is only on rare occasions like these that I think it should not involve our kids- this isn't a regular thing. I think his mom does lay guilt trips on him that he's not spending enough time with her- as a way to manipulate him- not sure if that is a factor in this.

TLDR: Basically, it seems like he tries to turn would be romantic situations with just us two into family things. He cheated on me several months ago, so making time for our relationship is important. Am I being unreasonable to not want his daughter at our anniversary dinner?
