Is this normal after an i love you?
Note, it is my significant other's busy time of the year at work, so when I say standoffish, it could be due to this issue alone.
My significant other told me she loved me a few days ago while we were hugging. I told it to her, as well. She has communicated but seems a little standoffish.
I know it is a big step to tell someone you love them. Maybe it is just a normal reaction and I'm just too nervous. Maybe it has nothing to do with that at all and everything to do with her work.
You should do something nice for her. Maybe a massage or some flowers or something.
Yes, it's normal. Relax and take it easy.
