Ick to the Valentine's Day anniversary - that was mine too!! This year would have been 8th one and I've been divorced about 6 months. I won't take the day off this year, but I think last year, I did. Do something nice for yourself that day, like a massage or a pedicure. Or both!
One thing I offer - my H's first EA was before we had even been married a year. I wish like HELL that I'd made him stay gone when I kicked him out then. But, we got back toether, worked it out and bought a house, car, ran up credit card debt, etc... and then had to split all of that 6 years later when we did divorce. It would have been SO much easier to make the split without all of that stuff... when I had a car, we rented, etc.
Let me just tell you that it DOES get easier. Every day hurts a little less. His emotional immaturity will cripple any relationship he tries to have. It IS hard to move on and accept what has really happened when this person vowed to love us, above all others... and we realize that was a lie, too.
Hang in there and post here! You'll find loads of support.
