My girlfriend never likes my facebook statuses?

[lg51]

My girlfriend of two years has recently stopped tagging me in photos, AND she has stopped liking my status. She is always liking other peoples statuses, my girlfriend will stalk my facebook and ask me about it but she will never like it.

She is protective of her phone always scrolling facebook, even before bed...we are not talking or interacting unless I start the conversation, we are not having sexual relations, and the only time I see her socializing is when other people are around.

I think she is cheating on me. What is going on?
She has also locked her phone her iPad and her iPod. She says she feels like she deserves privacy, but our phones being locked was never the type of thing we did. Her phone is always on silent and sometimes she takes it in the bathroom. When I ask her if there is someone else she gets upset and says here we go again accuse me.


But all the signs point to infidelity. When I asked her why she loved me she said "Because youre my friend." I said do you love all your friends and her response was no, love is a strong word for friends....so if she loves me because I am her friend, and she cant love friends because its to strong of a word...she really doesnt love me right?

Help me out
