Search Results: worry about other girls

So I have been dating this guy for about four months. Normally I spend every night with him but this week he’s made excuses such as being busy with work and being sick. He’s canceled on me twice this week. I had spent all last week with him from morning to night because neither of us had work. When I asked him if everything was OK he said it was he just wanted a week to himself. My other worry is he follows random girls on Instagram (most don’t follow him back ) From our hometown and the towns near us. In addition to this I recently posted an Instagram picture with him for the first time and he didn’t even like it. Not to mention he has no posts of me on an Instagram or Snapchat. When I asked him if he would want to put a picture on Instagram two nights ago (We were supposed to hang the next night) he said he was ready for that and would take the picture next time we saw each other. Lastly he’s always taking a long time to reply and yesterday he was replying fairly quickly during the day but at night it took him literally three hours to reply to all my texts. I also messaged him again asking if he would want to hang next week and is everything ok again after he already said it was and he left me on read. Do you think everything is ok? Would you be worried

So a couple months ago, there was a situation where two guys came to my house at 10 at night ringing our door bell asking for a girl that actually lived next door. I know they must've been given the wrong address. But any ways, after my mom sees them on camera at our door, she tells them to leave, but one of them tries to open the door because he seemed attimate about seeing this girl because she had something she said she was going to give them. As far as the other guy well call "N", he was calm and on his phone. After they leave, the next morning, my dad ends up figuring out that two of his tires are blown out. My mom immediately blamed the two guys, and they didn't get charged, because our front camera couldn't catch what happened. But long story short, my mom hates these guys with a passion, and i knew both of these guys partially because I've talked to them casually In school before. So i ended up talking to the guy called "n" and we ended up texting to each other on snapchat. I wanted to get his input on the situation, and we ended up becoming good friends. He told me he wanted to meet my parents, but i told him that my dad said he would "snap his neck" if he ever came on his property again. Even when i told him this, he was still attimate about talking to my parents about what really happened. So my mom hates them both and is 100% positive that they did it, and thinks that I am being disrespectful and ungrateful for being friends with this guy. And she won't even take ten minutes out of her time to listen to what he has to say. Pretty much she thinks "n" is a threat to me, but he tells me everyday he loves me, and that im the best thing that has ever happened to him and that he has never smiled so much until i met him. I am so grateful for him because i see so much more in him than my parents think they know about him. They don't seem to understand that there are people everyday that are wrongfully accused for coincidences. So what do you think about this?
