if we have three bestfriend including me the two bestfriend are childhood sweetheart i came between them am i wrong or right and i only like one between them i feel jealous if the girl i like talk with her childhood sweetheart is this right then give me suggestion or if this is wrong then give me a reson?

Hello darling, it's completely wrong

Explanation: The reason why you shouldn't get jealous is that its not good for you. It's ok if our BFF talk with the other people in fact I was like you and I got jealous about it, but that leaded me to a problem and we broke up. So, try to avoid this by being friends with the other girl, you can know her better, and who knows, maybe you're going to be best friends too! And maybe she's good person
Hope it helps
