Title: My clingy long-distance girlfriend asks if I talk to others when I'm busy —
what should I do?

Hey everyone, I’m in a long-distance relationship with a girlfriend who’s emotionally dependent.
She needs constant communication and attention. I’ve been trying my best to chat with her every day, even during off work hours when I’m really busy.
I actually need to sleep at 8:00 PM every day because I have to wake up at 4:50 AM.

But sometimes I end up sleeping at 11:00 PM after chit-chatting with her, so I only get 6 hours of sleep or less.
But sometimes, when I don’t reply quickly or miss a day, she’ll ask me things like, “Did you go chat with someone else?”
I often change the passwords for the social apps we use to avoid chatting with her, but sometimes I can’t control myself.
I end up pressing “forgot password” and then use my reset password to log in again so I can keep chatting.
I know she’s insecure and just wants reassurance, but it adds pressure on me emotionally.

I’m wondering — would it be okay if I only message her every 2 or 3 days during busy workweeks, as long as I still show I care?
Or would that make things worse between us?

I care about her, but I also don’t want to feel guilty for focusing on work. She says she loves me, but sometimes I feel like the trust isn’t solid.

Has anyone dealt with a similar situation?
How do you manage a clingy partner in a long-distance relationship when your schedule is tight?

Any advice would really help. Thanks.
