How did you know that was time to break up???

i’ve been with this guy for about a year and a half now. He’s 17 and I’m 16. things were really amazing the first couple months, obviously the honeymoon stage. We’ve had some rough patches in our relationship along the way but have been able to overcome them. lately for me, something feels off. keep in mind I have anxiety and overthink things all the time. I haven’t been able to see him for about two weeks because of Quarantine. Lately I just feel like he hasn’t been acting the same. I feel like he isn’t giving me the respect or attention I deserve. we don’t really have any conversations like we used to anymore it’s mainly what are you doing and stuff like that just dry. He doesn’t really complement me anymore either. About three days ago I told him how I felt about all this and he said he wanted to take a break but didn’t really give me a reason why he’s been acting different. I just feel like he’s sort of pushing me away and I don’t know what to do. sorry this is long
