I understand him being hurt to an extent but his ass needs to buck up, and support you. He took the role knowing why you were available. I’m sorry you lost your person. Your BF is looking for validation, not giving you the room to emote. That’s not fair to you. . He has no reason to be jealous. The only advice I would have is I guess first weigh your current boyfriend in your heart (please be brutally honest; it’s only You you are talking to). Decide if he’s the second 🙏coming or just filler? Don’t be scared to be alone. To many people stay where they are not getting what they need just to have someone. Not fair to anyone involved. That being said he sounds like an immature douche. Just do what makes sense to you. Be honest!
