So there's this girl that I like, and I want to ask her out, but the last relationship I was in didn't end well. We had been together for 5+ years and she dumped me very suddenly. I now am very cautious about who I develop feelings for, but I am scared that I'll have my heart broken again. But the thing is I think she likes me back, or so I think. I can't tell if my feelings are making me see things that aren't there or this actually is a thing. Either way, I don't know if I have the courage to ask her out and I need so guidance.
