Should I feel guilty?

Gabby

Well, I’ve been friends with this guys for over 2 years and we’ve always been friends but at the beginning of our friendship he liked me and I kinda liked him but I never said anything because he had this girl best friend and I’ve always had this feeling she liked him, this was later proven when they started dating, anyways the thing is a situation happened where he had to leave to another state for a while and had a long distance relationship, later then he found out that he didn’t love her anymore so they broke up, keep in mind throughout the whole relationship i kept my space never did I once interfere because I still kinda liked him but I wanted him to be happy, never told him anything. Anyways to make the story short he started texting me and we would talk on the phone for hours (still do), all night and we would talk about how we liked each other, yet we did nothing about it. He confessed to me that he felt like i was running away from him and i kinda was because of the bestie situation, I explained that to him. Well now I really like him but his ex gf( the best friend) I kinda know her, we have mutual friends so we chat sometimes. But the thing is that she’s been feeling some type of way with the whole breakup with him and us flirting makes me feel almost guilty. It’s been 5 months since the break up but we’re not talking to be anything serious, we just flirt and we’re going with the flow. Should I feel any type of guilt?

P.s they were together for 10 months

Another p.s I would like all their pics together so I definitely feel like a hypocrite too.

P.s “chat with her” as in if I’m like literally face to face with her I’ll say hi
