[Harmony♥]

You'll need to be compliant of his relationship. No matter who he dates, you may not like that person. Yes, she said 'I love you' too soon in the relationship, but that happens ALL the time. Love is a feeling, but when said too soon, it's just a word. She's definitely confusing love with lust or infatuation. That is a common mistake when a relationship is new. Maybe he could do better. But, right now, it's pretty apparent that he doesn't want to and that's something you'll need to accept. If he's happy, you should be too.
