My fiance

My fiance likes alone time which I totally get and respect. I am the opposite, I love being around people and especially her. She says she loves me a lot and stuff and we are perfect for each other, but her actions lean the other way. She used to like to snuggle but mot anymore, she wants to stay out with her friends when she saw me for about 2 minutes today, and I basically never get a hug, kiss, ect. unless I start it. We have lived together for a while and I have noticed increasing points where she kind of wants less to do with me and more alone time.

If you guys live together and her time alone (which she spends with others)is increasing,then there's a problem. You're correct when you infer that actions speak and if her's are leaning away from you more and more, then her words are useless. Your best shot is to sit her down and discuss with her what's going on with her heart in regards to the relationship that you 'share' because for it to survive, you and her both have to contribute to it equally.
