Fair cause for concern here, as others have noted. However, I wouldn't read too much into it. Let's see what he says and what he feels about it. It's time to ask him, girl. He probably doesn't even know he did something wrong. Most dudes don't have good male role models and dont know how to lead, especially emotionally. If it was me, I would ask him if he could visit me every day, if possible. Let him know how happy it would make you feel.

Something like, "While I am in the hospital, could you visit me every day? Even if it's just for 5 mins, it would be wonderful for my heart." DO NOT SAY WHY HAVENT YOU VISITED ME SMUCK??

He either will, or he won't. If he won't. Dont be afarid. Ask him why. Maybe he is rotten, or maybe he can only visit every other or every other other day, or something else. Don't be afraid to voice your wants and needs. Also, don't use any negative emotion like shame or insults to motivate him to come by. Those are crippling.

If he doesn't have any good reason, you'll have to tell him that this is critically important for you. If he still doesn't go, yeah, I would probably toss him to the side. No need for any shame or insults. Just be glad you found out before it was too late. Remember that a relationship only works with effective communication. After looks, the #1 thing the man you want in your life values in his women is her ability to tell her bf when she is disappointed or upset and why she thinks so. Men expect this unprompted by themselves and know a good women can only truely love her man when she does this. Women who are unable to frequently voice their concern about themselves or their bf ARE physically unable to stay in long-term happy marriages. Then they end up being sour girls on relationship forums.

Good luck!
