some advice

me and my boyfriend have been dating for over 2 years and it’s been the best 2 years of my life. he the sweetest, most caring person in the world but lately things have been different. for the past couple of months things haven’t been the same anymore. he doesn’t try to make plans with me, hold my hand, and i can’t remember the last time he complimented me... me and him have been trying to work things out for a while now. i tell him what i think that he needs to work on and he just tells me that he’s so sorry and i deserve better, then when i ask him what he thinks i need to do to better the relationship he says “idk, you don’t do anything wrong”. most of the time i feel like he sees me as more as friend than a girlfriend, i feel like he doesn’t like me like that anymore but he swears he does. and the thing is that i’m head over heels for him, i’m so in love and i’m very scared to lose him. however, if i need to let go i will if it’s for the best. i’ve just been so stressed out lately and i don’t know what to do, so if anyone has any advice, i’m all ears...
