How do i know she loves me?

okay so weve been best friends for about a year and a half and she is the best like we are the same exact person only im a guy and shes a girl and weve both been in seperate relationships and have helped eachother get through thm but for the past 5...

months she hasnt been in a relationship and its been about a month for me now we flirt all the time and we talk non stop were always partners when we get a chance we go over eachothers houses all the time and we were friends with benefits over the summer until we realized that this was pointless if we werent going any further thn that (yes as unmanly as this sounds it was me who put an end to this) we miss eachother every second were not with eachother and everybody is always telling me that she does love me and I mean we talk about how when we get old and are married all the time and im not sure if now I think that I love her and im not sure if I love her because im looking for love and its just easy for me to choose her or if I really do

Well I would say ya'll should give each other a chance!
den see wut happens next!

call her now. even if you dont go any further dont just stop. you can still be great friends. dont give up! dont just let her leave you behind. you have to do something.
