Am I being taken for granted ( please read this out)

I have posted this is other groups but I am in desperate need of an answer

I didn’t know where else to go, so I wanted to ask you guys if it is me being completely irrational or he is taking me for granted.

We are in a LDR and well everytime I want to talk to him he is always busy, had to go to the Gym or to hang out with his friends, he does this more than 3 times a week and I wait for him till late at night and by then I am upset because he know I have sleeping problems and won’t even bother to even leave a text to why he would be late, and when I confront him about it he would say I don’t even try to understand his situation and that all he really wants is to spend time with me and he spends most of his free time talking to me.

He is having a month off from job, while I am still in college and being in a medical field it can get quite hectic, but I always had time for him.

When I told him that I feel like I am being taken for granted and I am getting quite lonely in our relationship he tells me that I always complain about him and that he could never be good enough for me.

This week we had a fight regarding this, and I was really sad when in the middle of the fight he told me that he is going out with his friends, so I called him and cried asking him not to go out and that we need to discuss the situation, to which he replied he is already out and there is nothing he can do, and that it was my fault for pushing him away to a point where he finds that there is nothing to fix in our relationship and just kept the phone

After that he didn’t call or text me for two days

But I understand this because he was traveling, I called him at night to which he never called me back.

When he was back I asked him what is going on with our relationship and that I feel like I don’t matter much anymore and he said that I should have understood him because he was traveling and that I shouldn’t have picked a fight with him just the day before his traveling date.

Last night I waited for him till around 2... I am usually off to be by 10 and at around one I got a text saying sorry and that he was tired. I called him and asked him why didn’t he text me at all, to which he said he was busy, (he was at a party). And later on proceeded to telling me that I will never even try to understand him

I am sorry for this long post but please help me I don’t know what is wrong with me

Update**

Thank you everyone for taking the time to hear me out and listen to me. I read all the comments and considered each of them.

It’s just so hard to do it, I feel like a coward but my heart is so stubborn to believe that he could do me any wrong

It’s so hard to let go of someone you had so many plans with

But yes I do need to let it go
