My relationship (23F and 23M) is falling apart.

I’ve (23F) been in a relationship for a 5 years already with 23M (we had our 5th anniversary two weeks ago) and right now i feel like we’re close to the break up. I love him so much i would do anything for me and I KNOW that he loves me too. But right now he is sleeping next to me after our talk about it because in my bones i just know that something is wrong and we cannot talk it out. He told me that he loves me but that he cannot accept my behavior, that im somewhat irritating to him (and this behavior he tolerated or ignored for the last years and now he just cant ignore it anymore). I don’t really know what irritates him in me and honestly I’m afraid to ask.

I have been really depressed lately, without a clear reason and when i cried to him today because of it he told me that he doesnt know what to do because he tries to make me feel better (i don’t have Money for a therapy and ive been trying to not show my, really, devastated mood to him so he wont worry).

I know it is a bit chaotic, i feel so bad, i am so sorry about it but i really need to vent and i don’t have anyone.

I just really feel in my Bones that we will break up, I don’t want it, I will do everything to fix this relationship but I know I am tiring to him and that I’m really worthless cause he can’t even talk to me about things that are interesting to him because I don’t have any knowledge about them and I am not motivated enough to read about them.

I know that I irritate him sometimes, I don’t know why and I am so scared to ask however i asked him if he’s happy when he finishes his work and comes home to me, he said „no”. And when I am at home and he comes home I’m really happy because I miss him whole day.

I don’t know if there is any hope for us when he things of me that way?

He tells me that he loves me and he’s trying and he cares about our relationship and I believe him. I love him too, and I too want to try more and show him that I care about us but I don’t know what to do.

I am so sorry for my language, my mind is really chaotic right now and english is not my forsy language, I don’t use it often so it became a little rusty. So sorry.
