Healthy Relationships Support Group
No relationship is perfect. A long-term relationship requires constant effort to understand each other, fix misunderstandings, solve problems and continue to grow as both individuals change and evolve. How we deal with our misunderstandings is the focus of this community. Join us to find support, get advice, and share your experience with your relationship.
However, given your situation, to be honest, I'd probably do a little investigating. Not over the top (that will drive you crazy). I do think it's strange the ex texted him happy birthday, after not being in contact with him for years. I think there is more to that (more back history). That they reconnected someone else prior to that text (like facebook).
