Why are some of my iMessage text messages being received sporadically by my father

Question

I've searched high and low, but couldn't find any information regarding this particular issue, so if you know of a link in the discussions please show me.  Today my father received 2 texts from 2 seperate numbers by friends of mine.  This is troubling, and isn't the first time.  I am using an iPhone 4 fully updated to 7.0.4. I recently noticed that I was no longer sending messages as an iMessage (blue text color) so I investigated the issue within the settings function and didn't really see any differences there with the exception of the Apple ID.  I've always used my father's Apple ID and only once has this happened, the only difference was that I was receiving his messages from people in his contacts.  It is also important to mention that my carrier is Verizon and that we are on a family shared account with 4 members.  I don't think that any of the other members have ever received any of my texts, but then again I don't know if they are using just one Apple ID (I think they have there own personal IDs).  So it comes to this, do I need my own personal Apple ID?  If that is the case why do they offer the option of selecting what numbers or email addresses to choose to have my texts sent to?  Also in order for me to open an Apple ID I must be the owner of a credit card which I do not use nor do I have, not even a debit/credit card.  Anyway, that's it.  I don't need my personal life spilled into my father's life, we all have enough problems of our own!   Ciao and thanks for any and all help.

Anyway, I followed the steps you provided, and changed all of the settings including <-- Settings <-- FaceTime and Settings <-- Messages <-- Use your Apple ID for messages.
Just to be clear, while you have to use an Apple ID for iMessage and FaceTime, you should not be using that e-mail address to receive at or send from since you're using your father's ID.  Later in your post it sounds like you de-selected e-mail addresses that were not yours, which is correct, but I wanted to make sure you understand that you should not be using this ID for a contact point since it is not yours.
If your father is still getting your text messages from your friends, I suspect that either:
(a) after making these changes you need to turn iMessage and FaceTime off for a brief period, then turn back on, or
(b) your friends are replying to older messages that you sent from your father's Apple ID, or
(c) your father's iPhone somehow has your e-mail entered as one of the possible contact points for his iPhone.
If the cause is (a) turn iMessage and FaceTime back on since you've already turned them off.
If the cause is (b) see the last paragraph of my 1st post.  Send your friends a new iMessage and tell them to only reply to that conversation and delete prior conversations.
If the cause is (b) have your father de-select (or remove) your e-mail address from his iMessage and FaceTime settings.
