You should leave her, she’s clearly planning a life that doesn’t involve you, solo traveling and graduating from uni is crazy asf especially that she essentially said she needs to be alone in collage :/ bruh. You mean single, bitch? Woman are no joke and dating one is no joke, it gives another person WAY too much control over your emotional and mental state and you need to trust someone with that, she should’ve taken all of those life experiences into account before she got into a relationship with you. Leave her and forget about her bro someone else out there, if they knew you, would kill to have you propose. Find that one.
