Whinge away my lovely, God knows I've been doing my fair share of whinging these last few weeks!
Point 1, DP's collegues, they have obviously shown themselves to be arse's if the manager even agreed to employ an assistant, so don't worry about them two.
Point 2, DP phoning his mum and dad, does he see them often? I live 200 miles away from my mum and we speak about twice a week. How old is DP? I don't mean this to sound rude at all, but how would you feel if it was him telling you not to ring your mum? Maybe he could agree to ring whilst at lunch or after work, if it is effecting his work that much?
Point 3, I can hand on my heart say that stress doesn't always = miscarriage, when I got pregnant with DS1, I was 18, married, to my DH, who is 13 years older than me, my mum and I had fallen out over the wedding, she didn't come to my 'big day' which wasn't so big with out her, I was absolutely dreading telling her I was pregnant, I couldn't sleep, couldn't eat, I was so mixed up with being estactic that we were going to have a baby (who was very much planned, so in no way a shock) and then so torn the other way that I didn't want to completely wreck my already failing relationship with my mum. I lost weight, looked a state, I got ill one thing after the other, all from the stress, but the baby stayed, and was perfectly healthy, so please don't blame you stressing for the MC. It isn't always as straight forward as that.
Point 4, this laptop business and holiday thing. It is like I said the other day, I expect she felt like she was losing you a little when you and DP first met, it is what happens in new relationships. Can you afford to fix/replace the laptop? You can normally buy the part's off eBay for pennies, and it might cost you £30 to take it to be repaired unless you or DP know anything about fixing them. As for the holiday, if you don't want to go into the ins and outs of it all, could you tell her that you are planning on starting a family (which I am sure she will be more pleased about thean any holiday) so you are saving every penny for that? You don't have tell any time lines or anything, just a vague within the next 12 months or so should do the trick, then she won't be questioning you about from here till forever!
Point 5, work stresses, can't help there I'm affraid, I think stress just comes with jobs....
Point 6, your best friend. 11 years is a long time, maybe you have both just grown apart and in which case as sad as it maybe, it is the right thing to let things die down? On the other hand, if you want to make it work, arrange a night out, or a girly weekend somewhere nice or something.
Is that everything?
