liam, hate to be the barrer of bad news but this gun is already loaded, it just depnds who is going to fire it ,you or her.Just the fact that you have posted on here tells a million storys.Mate you are trying to fool your self sorry but despite what you have said the sad fact is you do not trust this girl and iam afraid you never will , even if she tells you that she wont do it again , every time she,s late home from work gets a text and says it no one important goes out with girlfriends but comes home later than expecd your mind will be doing over time . How i know this i have been there and believe me it will eat away at you , trust is the key here if you dont trust her you need to move on , or it will make your life a missery . Trust your instint mate if it doesnt feel right it probably isnt.
I know this is not what you want to hear but some times the truth just has to be said , please feel free to tell me to do one i wont be offended.Any way good luck.
