I was wondering which preposition is the correct one in the following context:
- My family and her family show love to themselves but I don’t have feelings ________ her and I try to look for other girls but I haven’t found anyone who can replace her and I want to settle down. We’re 3 years already in this relationship. Please help me.
The writer in the original paragraph used the preposition "for" while it is a little unidiomatic to me. I wonder if "have feelings for someone / something" is a fixed expression.
