Relationships advice (what should I do?)

Im 19 and I’m confused about my feelings about my relationship, a bit context my partner and I have been dating for almost 3yrs, I cant tell if our relationship started good but our first problem that i cant seem to forget was they didn’t get me flowers on valentines ( our 1st valentines together) which I think its kinda childish of me to get mad since when they asked me if i wanted one but i just said “I’m ok with anything “ so they didn’t do anything until I felt sad so I did tell them at the end but then I only felt guilty of not wanting it anymore cause Im embarrassed and we both got emotional, I want to talk about it but they wanted to go home but I insisted that we should talk first so they stayed, we both apologized to each other at the end. Now I always tell them that I really like receiving flowers i don’t care if its papers, plastic or the real ones since we are still in school but he keeps telling me that they want to give me more or like bigger and expensive so I told myself if that what they want then I’ll just wait for the future ( i recieve 3 physcal flower 1 is the flower we kinda argue abt). And (my perspective)since we’re in college now i feel like im the only one who makes an effort to make plans to see each other I tried to understand that they might be busy so I started to go to my partners house whenever we misses each other to the point that my mother asked me why does my partner never go to our house anymore.(extra) my partner is the type of person who avoids or like “lets talk about it tomorrow “ type when we have misunderstanding and I think i have anxious attachment thats want to clear my head before we go to sleep (so kinda cry when they sleep), eventually i got used to it, we’ll be silent for a couple of days and i’ll reach out to them and there’s other stuff that i dont feel comfortable with what they do (im not comfortable saying it) I keep telling them that im not comfortable and (whenever i seek comfort they do this and i kkeep on telling them to "this" instead but it seems like they keep forgetting it. And I also got blamed on something by their aunt, I told them to tell it to their family but they didnt, i just found out whenthat they never told them until they told me that their aunt is blamming me. Last November when I feel like i had enough they did the thing that made me uncomfortable instead of comfort again and we got really busy or they got really busy to the point im alone which I have noticed that im really relaxed and enjoying my own then we talked again that saying that somethings feels off after that i asked for space to think and when we got to meet each other again(dec17) we talked about us being better off as friends, I actually didn’t think ill get hurt like i thought i had enough to the point i wont feel a thing. But then dec25 they talked to me saying that they should’ve been strong minded that why did they give up so easily and we took a couple days to think abt it, then we agreed that we will try again and deep inside i want to give it a try maybe things will be different, so we are here now, I feel weird specially when they gave me flowers(last week), and everytime they want to do something together( I find myself enjoying alone )that i refused them( i feel guilty) i sometime get irritated when i recievce a message from them.

what should i do?

Please dont think of them something bad They are literally a good person and help me alot ( idk if THEY helped me or I help myself to be better for them)
