Why did my photos get transferred to my moms phone?

Okay, my mom got a new iphone 7, and when she was transferring her photos from her old phone to her new phone, all my photos from my Samsung ended up on her phone. Why did this happen and how do i prevent this from happening again?

My iPhone 5C Doesn't Charge?

I've had my iPhone since May and sense 2 weeks ago I haven't charged it but meanwhile if I held down the power button it would show that it has a low battery and needed charging, today I finally got a charger but it doesn't even show the low battery sign. I let it charge for 30 minutes and its still unresponsive?

What Does All This Mean?

We were trying to get back together(i have been the one chasing him and he was responsive but still cold and kind of meanish saying he doesn't love me but has some feelings and will take time to get comfortable to be expressive) and were fighting again. Said the worst things to eachother and he said to move on from him and go and date the guys that are after me. When I finally said ok and sent a fb date invitation from another guy. He said fine go get lost. Then like 5 hours later he texted on viber( i blocked him on my phone) like shame on you i can't believe youre going out with him. You'll come back but If you go out with him I won't ever take you back( he was telling me how he didn't want me and now this)., he sent a screen shot of his iphone text inbox the top one being saved as Anna saying I miss you(i'm wondering if he made a fake number and texted himself and saying i wasn't the only one playing those games and how that's why he wasn't paying me
any attention) and I blocked him. He messaged on whatsapp an hour later saying shame on you and i didn't reply then 20 min later texted with a different number saying shame on you and i didn't respond. He really didn't want me and was cold towards me and saying such mean things. That was 2 days ago and today was my date.
