I'm at a lose for what to do

Is it normal for after two months in a relationship to find yourself always angry at your boyfriend to the point where you contemplate in your head that you wanna break up with him? I'm asking because I've been going through a rough past few weeks with mine. I'll shut him out about my feelings at times because I fear something I say will upset him and I know he can't read minds but I wear my emotions on my sleeve and it's hard to miss when my mood has changed and I feel like I I expect him to know to keep asking me what's wrong until I say... I don't do this often but last night I sent my boyfriend a scandalous, sexy, and steamy picture of me in my robe fresh out of the shower and at the beginning of our relationship he would normally be all over that and showed me attention, however he didn't comment at all which made me feel not hot at all. The no comment is fine but a few minutes later he posted on his snap chat story about all the other snapchats he'd seen with girls and their puppy dog eyes which pissed me off.... And last thing but for the few weeks that Ive been in a rough patch with him there have been other guys on my college campus that would randomly come up to me and notice the small things I would change for my boyfriend that he never notices. And I get mad at that because totall strangers will go out of their way to compliment something I've changed for my boyfriend that my own boyfriend wouldn't notice. Am I petty or does that seem to be a problem for some of you as well? I really don't know what to do anymore and I've cried myself to sleep for the past week feeling ugly about myself.
