im the paranoid partner and my mrs is very trust worth and caring she means the world to me but i cant help thinking she just not happy with me, she always tells me she is and i just keep thinking she will go off with her ex which she tells me was a very stupid thing to think cause he trated her like **** and never went to see her but when we first got togeather he would comment on every face book status she put up and she would comment back with jokes and stuff she would also recieve txts off him and inbox messages but she would always show me the txtes and would show me anything i asked but in the back of my head i thought she was hiding stuff from me, her ex has a very good job and would not hold back from buying her stuff but he had a drink issue and i keep getting told buy my mrs that i have nothing to worrie about but it still at the back of my mind, we think its got alot to do with the fact i use to smoke cannibis alot wen i was young but i dont touch the stuff any more would this be the cause of the paranoider?
