<human>: Can you condense the text into a few key points?

I'm his first girlfriend (I've had two serious relationships before him, one of two years). We've been friends for years and are together for 5 months now.

I'm used to boyfriends that pamper me/give me compliments/are jealous. My current bf doesn't do that and that makes me feel very insecure. An example might be better here:

I wanted my bf to come over this weekend. I texted him to ask that and he said he would check it at home. 
Once at home, he didn't answer me, he texted about other things though. After our goodnight texts I decided to tell him why it was important to me. (Because I'm unable to be with him my birthday, because of "examweek" at my university).
He answered that I shouldn't worry, that he had said he needed to check it and tell me. 
That made me feel really bad.

We have situations like this a lot. He does something that makes me feel insecure and ask him if he still likes me, he says I shouldn't worry so much and he is dissapointed in me that I really believe he would stop liking me for something little.
But because he never says out loud why he likes me, I keep feeling insecure.
<bot>: my boyfriend doesn't shows me that he likes me and when I ask, he thinks I think he would stop loving me for something little and is dissapointed in my believe in him.
