Hi, you are where we have all been and others are still going through it. You 'MUST' start to get a poker face and be happy and positive around H and act as if. You must GAL and do some things on your own and then when you get back act like you've had the best time ever. This is about you first, so try and stop worrying about H. You gotta stop the begging, pleading and intiating the sex.
Now, believe me, that was all easier to say than do, but the more I say it the easier it becomes. I had my 7th anniversary recently so there is definately something in the 7 year itch thing IMO.
If you are staying in the house together for the summer for the girls, maybe you can suggest the D papers wait til after that and you have a job.
