<human>: Summarize the given text in a few sentences.

I'm gay single and I was invited to go to see deadpool with my sister with her and her boyfriend. I didn't think to ask if it was on valentines day because she said she would see the movie when it wasn't busy.

My sister was in foster care so I like to spend time with my sister because she wasn't allowed to she any men/boys when she was in care and her boyfriend seems nice but I don't know him that well spoken to him like maybe 5 time but she likes him and that's all that matters

Fast forward to right before I'm writing this my sister is on the phone with my mum I'm upstairs on my phone redditing, my ma shouts up to me if I'm still going to the movies on SUNDAY I say yeah don't think nothing of it, then right after I read something on the/my front of reddit saying remember valentines day is on SUNDAY.

I would be willing to go with them if it was any other time of the year so to say because I missed my sister and like spending time with her but it's valentines day and I'm really confused on how to approach this. I don't know if I'm over thinking this or if it is weird do I pull out or go with my sister on a date on valentines day with her boyfriend
<bot>: invited to deadpool with my sister and her bf on valentines day said yes and feeling weird about it now
