My brother and his fiancée were together for near on 6 years, then he started something with another woman behind his fiancées back, to which she was heartbroken (understandably), they had a beautiful home together to which he moved out until it sold, she agreed she didn't want any content of the house other than a bed, which he agreed with, and he also agreed she could stay in the house till it's sold and he'll move back to our parents and he'll carry on paying his half of the bills and he 'understood' she was not the one who caused this, and didn't want her to be out of pocket.
This was 6 months ago, he moved on with a woman who had 2 children (the woman he was talking to behind her back), and he moved in within a month, and as much as me and his fiancée were close, we drifted apart, which had a big affect on my lo.
Now 6 months down the line, she (the ex fiancée) has got back into contact with my which I'm thrilled about, she's a lovey person, but my brother and his now girlfriend are not happy about it, it only came to light as we re added one another on Facebook (probably a wrong move I know) but I wanted to know if I'm being unreasonable to have a relationship with his ex? who was a big part of my sons life, and mine for nearly 6 years, throughout my pregnancy, birth everything.
