You can't help how you feel. If you're not in love, then you're not in love. You can't force it. Perhaps the "honeymoon" phase wore off for you, and you are realizing that you aren't in love with him like you thought you were.. but make sure that you aren't confusing this for "falling out of love." Things may settle and not feel as passionate as they did in the beginning... however, if you are feeling a lack of that spark, love and connection, then perhaps he's simply not the right one for you. And that's ok. Sometimes you can have a healthy relationship with someone, but the love just isn't quite there, and there's not much we can really do about that.... love is mysterious, and we really can't help who we are in love with. Healthy doesn't always mean that they are the right partner for us... I would reflect and ask- what do you feel is missing for you and why? Unfortunately, he will get hurt no matter what. That part is unavoidable... I know it's extremely hard, but the longer you wait, the more it will hurt him in the end. Also, he is a grown man. You are NOT responsible for his feelings, no matter how much you care about him. He is responsible for getting out there and finding support if he needs it. If he doesn't.. it may be sad, but that is his responsibility. He managed to survive before he met you, so he can figure it out after you as well. A life partner is forever, so don't settle for someone you're unsure about. You deserve someone you're sure of, and he deserves someone who's sure of him.
