I mean hell, some insecurity is fine. I get that she, like Jake, is still dealing with trauma from past relationships and trying to avoid the same mistakes. I think she's going about that in a completely terrible way, by getting over-attached to a man who had been very up front about the relationship being a casual fling to get over his ex, but I get it.
What frustrates me is that, at least as far as I've seen(just getting to her conference scene now) she doesn't have any real development along that path. There's no growth from her. There's a bit of growth from Jake, when it's convenient, showing that he can open up and bond more meaningfully with V. But it still feels like everything in the relationship needs to happen on her terms, that she can't give him more than a few inches of space to work on his project or save his daughter before acting like an abandoned puppy or a territorial mama bear. Even when she does things that are ostensibly to help Jake, like attending events to help the battery project or distracting him from his troubles, her clinginess always marrs it in some way.
I haven't done dedicated paths for everyone yet, but the two characters I went deepest with in my main run, Jasmine and Maggie, have definitely had growth and been explored as characters with legitimate depth. Allie too, and while I haven't done a ton with Nat there's plenty of obvious hints at something deeper beneath the surface. Like, fuck, Alexa and Kris have had more character development than Veronica has!
I hope that, in future updates, Jake will set some boundaries with V. Not just about other women close to him, but in general. It's not healthy for either of them if she fixates on him this way and he doesn't reciprocate. He is, at this moment, not capable of giving her what she wants, and she's too desperate to make things work that she can't or won't see it. Either she needs to back up a bit and be willing to give him the space he needs to sort his shit out, while dealing with a couple of her own issues, or they need to go their separate ways. Obviously I know my pick for my main run, but given she's a central love interest the former is going to need to be dealt with too.
