Hey did you ever find out what the deal with this type of scar is? Is it a cold sore?
he'll need tested to see what his status is. assume nothing based on his mom having cold sores.
it's best to reply to posts here and not send pm's. typically I don't even read them to be honest.

you aren't spreading it to new places - this is the way the virus works and is completely normal.
no need to change your toothbrush after every cold sore though it's recommended you do so every 3-6 months in general anyways so if the timing works for you as a reminder to do so, just keep on doing it.
has your bf been tested to know his own herpes status? even if he can't recall ever having had cold sores, he very well could have hsv1 already. worth a test to see what his status is.
Even though you don't have health insurance, if you get a prescription for acyclovir, you can get the 200mg tablets at walmart for under $4 to treat cold sore recurrences. If you have a regular doctor, you can give them a call and ask them to call you in a prescription. Oral antivirals help speed healing of cold sores faster. Just something to think about. If you start them at the very first tingle of a cold sore, you can actually sometimes avoid a full blown cold sore which is always a good thing!
As for what is going on now, since you still have tingling I recommend avoiding contact with your partner at this point since you don't know his status. If this isn't better by monday then it is worthwhile to see a medical provider for follow up to make sure this isn't something else going on because at that point it's definitely atypical for cold sores and requires further evaluation. Meanwhile continue to use topicals. Aveeno cold sore ointment with propolis in it is under $10 I think. Propolis has been found to speed healing of cold sores. You can also just continue to use a lip moisturizer with spf in it and periodically steep a tea bag and use it as a compress on the area to help with pain, itching and also to help reduce the redness that makes this more noticeable. I'm all about the cheap :)
