Relationship worries !?

A few tidbits, friend conversation on FB ( she left it open and I looked ) , it ends the chat with " thank you for "ALLOWING" me into your world this evening. Maybe we can have more chats in the future if you are open to the idea. When I asked about her new FB " Friend " she got seriously belligerent, saying that I was accusing her of cheating and where would she find time to do such, funny enough they work for the same entity, in different departments, prior to that had stopped kissing me intimately, saying that my stubble irritated her skin, that is after more than a year of having such, and I had to initiate sex at all times without a kiss. Albeit we do not live together but spend most week ends together, she bought me a robe for Xmas to keep at her house and a card that says she adores, me, days with me, nights with me and life with me !! Should I be worried, content or run ??? Thanks for your input
