It's normal to feel like that.
DP was ALWAYS HERE. He was there when I woke up, he was here when I came in from work, he was here all evening, he was here all night (obviously).
He got a job that involves one later shift a week and a Saturday morning.
It was bliss, I could potter about as I pleased, not have the TV on, not have every light on in the house, go to the loo without shutting the door, scratch my arse, cook whatever I fancied instead of him cooking.
Got home last Thursday night, looking forward to 'my' evening. The bugger had swapped shifts because he had a cold. So not only was he here, he was flumping about sniffing and sighing whilst wearing the Dressing Gown, all the lights were on, the TV, laptop and phone were all going at once and he'd made some foul Ding Dinner where he'd forgotten about the need for vegetables and had drunk all my orange juice.
I had a right cob on about it. One night a week without fucking 'comedy' on the TV, laptop and phone. One night a week without feeling like I'm still at work from every fucking light being on all the fucking time. And he selfishly felt ill enough to not spare me that.
I got over it. I made him drink elderflower syrup, made ginger, lemon and honey tea and got the bugger back to work before he could ruin my Saturday morning as well feeling better and functioning again.
If he changes jobs so that he doesn't work an evening and a half day at the weekend anymore, I'll cultivate a more regular gym habit so I don't kill him get some exercise.
