<human>: Can you give me the gist of the text in a nutshell?

I've been with my girl friend for 14 months and I really do adore her. She's been so good to me and has supported me through thick and thin. 

As with any SO there is a sense of property where one might think, "Hey thats mine! Don't touch!" or just jealousy. I totally understand both of these things as I have experienced them myself. My girlfriend is very possessive of our relationship and can get very jealous very fast. She is rather emotional. Her father cheated on her mother and left at an early age which causes her to detest lying. If anything seems even remotely off to her she will shut down. There are times where I've done nothing and she will display this reaction causing a rift between us for a brief time. Since I go to university while she is in her last year of high school, she us very suspicious of any weird activity especially regarding other girls. She gets defensive and somewhat cold towards me if I mention a girl I met as friends or other happenstance events. She reads into a lot of my actions and words which causes anxiety and doubt on her end.  She has repeated this behavior each time a girl has come into question or she suspects me of lying. Its gotten to the point where I feel very nervous after speaking to another girl over social media or in person. I feel like I am hurting her and I am so worried of her reactions since I know it will be like a bomb going off. 

What can I do?
<bot>: I feel extremely uncomfortable talking or hanging out with other women since my girlfriend is very possessive and sensitive to our relationship. I feel like I am hurting her talking to other girls sometimes and I dont know how to shake the feeling off.
