Befpre dp and i were together, his best male and and his girlfriend split up for a while as he had been seeing someone else. Dp was also friends with the girlfriend and they lived a few minutes away and they all went out alot and on holiday together. When they split up , they agreed his (male ) friend would stay in the house they owned together as the girl's parents lived 30 mins away so she could stay there. The girl was worried when they split up she couldn't be friends with my dp anymore as he was her boyfriend's friend. The boyfriend asked my dp to tell the girt that my dp and her could still be friends if they split up. So he invited her over for dinner so they could chat and also hugged when she was upset. He also she could stay with him for a while if she needed to (he only has a 1 bed house). The girl and dp's friend got back together a few weeks later. I haven't met dp's friend yet but i already feel this girl is a threat and that the cares a bit too much for her. I have told dp this and he's assured me there was nothing it it and he only invited her over , said she could stay as he cares for her as a friend, but i have a nagging doubt.Am i being silly?
