What is she thinking?

talk to her. tell her how you feel, ask her where she sees this going. if she is planning on marrying him, why is she sleeping in the same bed as you? clearly there is something wrong her. ask her to be honest - and you can be patient and stick around and give it more time and see where it goes. if there are more signs or her wanting to get back to you, then take it as it comes. you'll either get closer or you wont and then you can take it from there. as for how do you make her want you? you cant. she either wants you or she doesnt, it should happen naturally. but what you can do is be a gentleman, be patient, kind and treat her well. these things matter when it comes to choosing who we want to be with
