Ooh Megrim, he sounds like he's a keeper

OP, my DP is rubbish at birthdays, but instead of getting stressed about it, I know to plan something myself. Last year, I had to take the DC to a softplay party on my birthday, but stopped on my way home and bought myself a bottle of bubbly and a takeaway for all of us. He generally does crap presents too, but I'm not bothered any more as I just buy myself what I want! He's a good man, but really doesn't make an effort at birthdays/Christmas/mothers day/valentines day and all the rest of it.
In fairness to him, he doesn't expect anything for any of the above either, he's just very laid back. I make things happen for myself these days.
I have just booked myself a birthday party for later on this year. I am turning 30 and have never had a party. I told him this a few months ago. When I spoke to my DM, she had suggested a party, but he had muttered something along the lines of 'thought we'd just have a family meal at pizza express'. Hmm, no we bloody won't! So I've booked myself a party. I won't be disappointed as I've sorted out exactly what I want, won't be having to drop 'hints' and be pissed off if he doesn't work it all out.
Take matters in to your own hands OP! It's the only way sometimes! And yes, if you want to book a hotel room for yourself for the night, just do it.
