My iPhone 5S won't charge when plugged in?

The phone turned off because it was out of battery but now when I plug it in to charge it says not charging and when I take the plug out it says charging. I had this problem once before but it resolved on its own quite quickly. It's been an hour and no change.

Sleeping/Waking up problem?

So this has happened to me too many times before. I set a total of 7 alarms on my iphone and placed it on my bedside before going to sleep. I woke up to the sound of my mom telling me to wake up but no alarm and this was an hour after I set my alarm. I checked my phone and all the alarms were off so that ment that I had opened my phone with the passcode and turned off all of the alarms. Also the network was turned off witch i never turn off so I really don't understand what's happening here.

I'm really sad and desperate?

That guy I know from school told me that he love me and I did too then I told him that I'm not sure if I love him or he does because I just felt so that time then after that I lost my iphone so I couldnt talk to him for a while then I bought a new phone and we talked and I said sorry and we talked like nothing happened but he still I think love me and care about me but not like before now he is ignoring me and he is not talking to me much and by the way I didn't see him in a month cuz I traveled and I will be back to my state in a while… Do you think he lost interest in me or something what could I do to make him want me?
