What should i do to stop overanalyzing and overcomplicating and potentially ruining this F(22) with M(26)?

So, I am in a relationship with a wonderful person who i love a lot. He is my first boyfriend and I feel lucky to have him in my life. We have spent the majority of our relationship with distance so the past few months that we see each other very often i feel there are some issues rising. I think that i gotten used to the distance and the idea that when we see eachother we spend that time together because it's limited and there are a lot of emotions and now that a more normal everyday routine is settling and we see eachother for 4-5 days every 5 days apart I find it a bit difficult to adjust.

For example he may want to spend some hours s during the day when i visit gaming with his friends and that made me upset at first a lot but realised that this is not right and i have to stop. I. think it was mostly that i hadn't gotten used to us doing separate things that much when we are together and all i have experienced in the relationship is when we are together we spend it together so i found it strange that i am not being prioritised. I started accepting it telling myself it's not something wrong he needs this but some sort of negative emotions still preserve and I don't want them to i want to send them away.

Or when we wake up he goes straight to his pc and if i don't ask for it he would keep gaming the whole day, so i feel that he doesn't need together time when my logic says that is not the case. Most of the time i say to him that he can game as many hours as he wants but i want the rest of the day for us to do something that i also want like going outside but he says no almost all the time and instead we watch anime or something else which is something that i enjoy, just want some outside time. I like gaming as well but I don't have a pc so i can't always join and sometimes i say lets go to an internet cafe to play together but he wants to do it alone with his friends and doesn't like internet cafes.

I hate some thoughts that enter my mind like if he is gaming for days straight with his friends when we apart why is it such a big need to do it this much even the days we are together? And I know this is toxic thoughts maybe due to lack of relationship experience and shifting from long distance but sometimes I can't control them.

tldr: I think my lack of relationship experience is sabotaging my relationship. What should i do to not make my thoughts toxic ?F(22), M(26)
