Do you for see this going anywhere in the future?
Yes as when two unhappy married people get together they tend to stop working on their marriage, and
they get selfish and caught up in each other and go through misery and pain, until both families suffer even more than ever.
Sounds like you want this to be a happy ending, but for someone it won't, and usually that's the unknowing innocent party at home without a clue, especially the children.
Your marriage is what you make of it, so don't be distracted from that, go or stay. Just don't be stupid!!
