I have unconditional love for my son. I love my husband very deeply and would forgive many things, but if he abused me or something I'd leave. I might still love him in some way, but it wouldn't be the same.
Yes I do believe in unconditional love. Are there one or two things that might make me leave my husband? Yes if he abused me I would leave him, but I truly don't think it would make me stop loving him.
To some extent, but I see that as a bit more extreme and dangerous. Not that deep love and being willing to work through hardship is good, but never giving up on someone regardless of their actions could be dangerous
