I know what it feels like , as I am sure everyone here does, to have the rug pulled out from beneath you. Hearing it twice is more than double the pain though, and I would hate to see that happen to anyone! So I encourage people to learn from my mistakes! I do not think anyone can afford to get comfortable in a relationship and /or wait for the "right time" to start working towards improving the relationship. That is why I think you should go to counseling, or find some other way to work on your relationship.
There is always hope if I'm responsible for my own behavior.
