<human>: Condense the text into a few key points

25[M] dating 25[F]
So I've been dating this girl for 4 months now and we do long distance (3 hours to be exact). 

She is a super sweet girl and very loving and affectionate towards me...is a great girlfriend for the most part and is very loyal.

Well lately, like the past month, any time she goes out or goes out with her guy friends or what have you she will end up not texting me goodnight or that she made it home safely. I am not the boyfriend who wants to hear from her ALL night long but I am the boyfriend that needs to know shes home safe or at least staying at a friends house. hearing her say goodnight even if VIA text makes me happy and allows me to sleep easy. Multiple times now, about 4 or so, within the past month...mostly all when she goes out...she doesnt call or text me most of the night until later in the afternoon the next day or in the morning as soon as she wakes up. Usually consists of "Her friend stole her phone", "Phone dropped out of her purse at work and didnt realize till she got home"....I can't tell if I am being paranoid or what because I get super annoyed and mad when I have to sit around all night and the next day just to know she's ok? This is the ONLY thing I ever get mad at her for and idk.... shes teh same way if I dont text her while im out or what have you and she gets really annoyed if my phone dies while I'm out but I always text or call her as soon as I get home to let her know im home and safe.

Any suggestions on what to do and how to handle this so I dont seem smothering, jealous...etc?
<bot>: Girlfriend goes out and an excuse ensues as to why she didn't text me goodnight or that she's home safe and I get mad over it.
