I have done this too, even in a different context of "this time, he's/it's different". I hate that pain and heartache are part of it, how we perhaps are more skeptic or reserved because of past experiences, but I know that's also a part of life. And part of protecting, guarding ourselves. And to also know, there's nothing inherently wrong with falling for others quickly. If anything, it shows how deeply we love and have the capacity to give and receive it. We should never punish or berate ourselves for forming that emotional bond. Even when it's hard to see what forever can mean, hopefully they treat you with all that you deserve, and you can know your worth and not let anyone dictate differently.
