I moved in with my boyfriend and his DS (22) about 7 months ago. We have been a couple for nearly 3 years and are engaged. His DD (26) moved back in with her dad at the same time as me, after a few years away.
His children are lovely, outgoing and very popular. I thought we got on okay, though I often feel very awkward and the odd one out due to my ASD. I often worry I make them feel uncomfortable when I'm around and sometimes delay coming home until I know DP is back.
Anyway, yesterday evening I got back home. Only his DD was in, doing some cooking. We talked a bit, I was trying to be pleasant etc because it feels rude to go past without saying anything.
The conversation finished and I left the room, as I left I then heard her say quietly, "Fuck off, you're stressing me out"
I don't think she knows I heard but now I feel very upset. I told DP but he thinks I might have misheard or maybe it wasn't directed at me. But it must have been aimed at me because nobody else was there! I don't know whether to ask her or whether that would make things worse, what do you think? I already feel like an outsider here and this seems to confirm it.
