Girl signed her card to me “love from” with a kiss. Does it mean anything?

I’m good friends with this girl who I first met on a fan group on Facebook and we later met up in person at this event we were both going to. At that time she had a boyfriend and we didn’t speak for long.
Despite this, we stayed in touch and we’d message on and off over the next two years. We could go by long months without speaking but then one would message the other about something (usually 50-50 who started it) and then that would trigger a much longer conversation catching up with each other.
Earlier this year, she became single again and mentioned she was in London a lot. I asked her if she wanted to meet up for dinner next time I was there (seeing a West End show) and, even though she said she wasn’t going to be around that time, she messaged me again days later saying she’d be up for joining me on future theatre trips.
We finally met up again for dinner a few months ago and then last week went to our first show together. Both times we seemed to get on extremely well, we had a laugh and have so much in common.
While in the theatre, to my surprise, she gave me a Christmas card. She said she was giving all her friends cards and I asked if I could open it then. She said “I only wrote Merry Christmas”, but I opened it anyway. Instead, there was a lovely message inside that ended “I look forward to going to more theatre shows with you” and then signed it off “love from [name] x”. A quick caveat to all of this is that we’re both autistic and so the normal social cues don’t necessarily apply, and I don’t know what she put in her other cards either, but nevertheless I found it curious.
What do you guys think? I really like this girl but could this potentially mean anything as to if she likes me in that way or not? Thanks!
