My fellas 10 year old daughter is jealous?

We have only just started seeing her again after 4 yrs (no fault of ours her mom got jealous when we had our son). in those 4 yrs we have two girls, when my b/fs daughter heard this she was shocked but seemed d. i was a bit worried that she would take a disliking to the girls but as she is a tomboy it has been our son who she is jealous of. she hates the fact that he sometimes asks to go to work with their dad and the fact that he has his own room (she has to share with two sisters) and generally all the toys and latest computers and trainers he has got. my boyfriend has always paid kid support and when he was in contact always treated her and helped her mom out by getting clothes and school uniform etc.. he even has a bank account which he puts money into for her along with our kid ren. he wud love her to have all the things our kid ren have got but knows if she did her mom wud sell them to help support her 5 other dadless kid ren how do we deal with this? my boyfriend had been split with his ex for a month before he found out she was pregnant. he as always seen her on and off, he has never lived with with her and and her mom. he is not on the birth certificate and his daughter does not have his name. we have 3 kid ren together, who all were planned and have my b/fs name we are getting married and all this just makes her even more jealous
Answer
Maybe (if you have space) giving her her own space in your house would make her feel welcome? even if it is a small cupboard or chest of drawers, some kind of space that is hers. then she will feel more like a part of your family as well, more like she belongs in your home , than the poor relation that comes to visit e so often. you could even get her all the stuff that your boyfriend longs to get her, and ensure that it is kept at your house, in her special space. a thought, hope it helpsnice luck =d
