Hey, I have been a roleplayer for a long time. I have a long past of letting other roleplayers down by leaving roleplays abruptly. A lot of it was my life at the time. Now, I always feel like I don't know what to do when I roleplay with someone for a very long time. I'm worried I have not accumulated enough long term experience to understand how to make a good roleplay.

Talk witb them, work out ideas, write down what you come up with or save a message with your ideas list. Just because it's not usable now does not mean it may not come in down the line. 

Planning and preparation can go a along way to helping you keep track of a longer RP. Also keep track of your changes and items. Gives you less to worry about. 

And experience, just learn from your mistakes. Youl soon find out what works and does not. Planning and prep makes life alot easier though. Keeps momments of panic down. :)
