Your current boyfriend is going to have to deal with his insecurities and get over it. Jealousy is going to be his eventual downfall if he doesn’t quit while he’s ahead.

I know, I used to be just like him.

However, if he is unhappy with this, maybe you need to make it more clear to him that you are asking him due to his credentials not as a favor as an ex-lover.

If he is still not a happy camper, then I would say his maturity level is not fit to do this with you no matter what the cause is.

It is ethical as long as you treat him like a guest speaker and not as your boyfriend or ex-boyfriend.

If your current boyfriend can not handle this, then he is not emotionally stable at all. You either need to sit down and hash out his insecurities, or if he can not do that in a rational manor then you simply need to dump him to. It’s not healthy to be in a relationship without trust and can spark jealousy.

I can not believe I’m giving you this advise, if it was a different question I would urge you to find another way to teach youth how to get an education without the military. Such as scholarships and what not. Plus, the reality of getting good useful paying jobs from having the “military” on your resume is getting slimmer and slimmer everyday. In-fact some jobs turn down people unfairly due to them being in the military, I would say it’s not a wise option useless you plan on being a “dog of the State” for the rest of your waking life.

Being that your ex was in the armed forces and it’s the message you want to spread to the kids – why not see if your ex can get someone he knows to come tell the kids the same thing? That way everyone gets the info and you and your current boyfriend still have a good relationship.
