This evening my boyfriend and I were in the car with his Mum, just talking about upcoming dates and she told him that they're going away on holiday for a week next April for his sister's 21st birthday, him and all their family. Bearing in mind our anniversary is on the 6th April, I said, "Do you know the dates? What about our anniversary?" Which got a very snappy answer from her saying "I think his sisters 21st is more important, really." He is 18, I'm 17, 18 next month, and we've been together 2.5 years. His Mum has never particularly liked me and I've never known why. In my opinion, our anniversary is very important to me and I want to spend it with him. I understand it's his sisters birthday and would be willing to pay my own way but I do think if he has to go away with them, I should be allowed to go too, as we're a couple and that's what couples do. His entire family is going, aunts, uncles, grandparents, cousins, and I do think it's only fair that I should be allowed to go too, as we're in a longterm adult relationship. It's not as if I expect them to pay for me but I really think our anniversary as a couple is important. He hasn't said much, just mumbled something about having not seen his sister for a long time as she lives away. I was just wondering if I'm being unreasonable to expect to be able to spend our anniversary together, or if I am justified in being upset by this.
I forgot to mention that it's not a holiday abroad, it's just camping for a week in Devon. Nothing major. But yes I do understand that some people consider anniversary's only when married, but we don't. We're not just a couple of kids, we're a serious couple who've been friends for 7 years and dating for 2.5. Of course I get that he should see his sister for her birthday but I just think that any other older couple who've been dating 3 years by then would be allowed to go together so why does us being only 18 make any difference?
