Last year I fell pregnant, and everybody was thrilled, except my husband's younger brother's girlfriend. She'd only been going out with my brother-in-law for 10 months and she's 26. Whereas I was nearly 31, married for two years etc. Anyway, when we told them she didn't even congratulate us (she just said, 'really? was it planned?'), then ignored me at a few family get-togethers (having been weirdly clingy prior to my pregnancy). Last Christmas day, she fled the room in tears when a great aunt asked me about the pregnancy, and later told my mother-in-law (her boyfriend's mum) that she was upset because I was having 'the first grandchild' (which, considering I'm older, is pretty normal). She also told a complete lie, and told my MIL that I had 'stolen' her favourite names (we'd never even discussed names!). Thankfully my MIL believed me (I've been with my husband for seven years and have a great relationship with her. She also acknowledges this girl is a bit odd). She's got a troubled past (alcoholic mother etc), but is also prone to lying and tells contradictory stories about her childhood so I'm not sure how much of what she says is true. Think a young Heather Mills! My MIL always excuses her behaviour by saying that she's had a tough life. But my own father was a shit, and I've never used that as an excuse to behave badly. Anyway, shortly after I gave birth this June she announced that her Pill had failed and she too was pregnant. She completely ignores my daughter (or makes snidy comments about her weight, cradle cap etc), yet bangs on about her own pregnancy (she went out and bought 400 size 1 nappies at the 10 week mark!!). I know I should focus on my gorgeous baby and lovely family, but everytime I see her I just feel so angry and resentful. I feel like she took a happy, lovely time in my life and tainted it with her weirdness. Then got pregnant just to get one up on me. I also feel my MIL should have stuck up for me a bit more, instead of feeling sorry for her. Am I being unreasonable to a) hate a pregnant woman and b) to still feel wound up about this?
