Context always helps! For a text like "Hindi muna ako mag-eenroll this semester. Pero ayaw kong magsalita ng tapos dahil baka dumating ang perang pang-enroll ko."
What you want to say is:
I want to keep / leave my options open.
I will never say never.
I won't make a final decision on this matter until I get more information / pending more information.
Examples:
I won't be enrolling this semester, but I will keep / leave my options open as some money may be coming my way.
I won't be enrolling this semester, but I will never say never. There is still a chance that some money may be forthcoming.
I won't be enrolling this semester, but I won't make a final decision on it for now as it is still possible that some money may be sent to me in the foreseeable future.
