Relationship Trouble.

I've been with my boyfriend for almost 11 months now and he's honestly my best friend. He's the one im most comfortable around, the one I can tell anything to, the one who has been there for me through so much. Our relationship has been really good all this time. Sure we fight, but usually it's about small stuff and nothing threatening to our relationship. Lately, we have been fighting over things that are bigger. It started off a few weeks ago I was at his house and I was just playing around on his computers, and I wanted to look at his photos, he literally walked over and turned it off. I do have trust issues so it set off alarms in my head and I got really upset. I trust him and it just made me feel like he had something to hide. Finally, he showed me everything on there and there wasn't anything there. Later that night, I saw some pictures backed up in his google photos of a girls feet he had taken in class.. apparently he thinks feet are cute and was too ashamed to tell me. I honestly didn't care if he liked feet, but he did take pictures of another girl's feet and am i wrong for being upset, and he didn't even tell me, I had to find out. I told him I would let it go, but I wanted him to show more effort into how he treats me because it really hurt me. Well I haven't seem a tremendous effort.. This past week we got in a fight because he wanted to be friends with this girl he had previously been friends woth but they didn't talk anymore because they just don't have the same paths anymore. This girl has lied about his best friend and she's just a bad person so it confused me as to why he would want to be her friend anyways. We fought over that.  Then today I called him to make sure he was up to get ready, and I said "Dont forget to shower and brush your teeth and all that" because he can get lazy and I just wanted him to make sure he got ready and took care of himself. Then later in the morning, I asked him if he showered and everything and he told me he did. I believed him. Then when we were together I could tell he didn't and I asked him and he told me no he didnt. Like, all he had to tell me is " I dont want to shower today" or something and it would have been whatever. I know it's a small thing to lie about, like im not sure if it should even matted. But it's still lying and if he can lie about small things, he can lie about big things. I'm completely honest with him always, I never want him to hurt and I never want to be the cause of it. It makes me sad that he can lie to me. I'm not sure what to do, should we take a break? Do we sit down and talk, and what do i say? I'm not sure. Am i overreacting? I just want to be treated right, and I haven't felt very happy lately because it's hard to trust him now and I love him, I want to make things work as long as we are both happy and want it do. Any advise?
