Why the f should i??

Ha sorry not to be so serious, but my "mum" left when i was well young (young enough i dont even remember), my brother adam (who basically brought me up - haha poor lad lol) got back in contact with her again recently and wants us (me and her) to meet. sorry but i cant think of anything worse, it makes me sick!!! he has given me the best life ever iv lived all over the world and really know exactly what i want from life, we are so close and i dont need a "mum" sorry ino its silly lol but really i have amazin mates and my bro is fookin awesome so im not upset its just ticking in my head lol! wat do u think... adam (bro) is biased cos he thinks shes changed... ino she aint.
