Is there like a main questline for every character (i know there is for isabelle and kate) but like i end up hitting a wall really quick when talking with Jacklyn or Mrs. L is there something im not getting?
No, not Main Quest lines, but they do have "free floating" routes that run alongside the Main Routes. If you're wanting to get further along with Jacklyn her path is kinda tangled with Flora's path. Mrs. L is at the moment mostly her own thing, and as far as memory serves should be pretty straight forward to get going. Just talk to her and she should start up her Quests.
