Mike,
At the moment your wife is telling you things that are blatantly and obviously lies designed to pacify you while she continues the destructive project that she has embarked upon.
She feels that if he gets out he will leave her alone and go back to his GF and he won’t contact her.
Think about it; if she really thinks he is going to do that, why is she continuing her relationship with him? Why is she sending him money and gifts? Nobody does that if they think a relationship is a dead end.
She says she has feelings for him and that if she ends this now he could tell authorities and she could land in jail herself.
A totally ridiculous attempt to use your love for her to emotionally blackmail you into letting her continue her affair with this piece of crap without opposing it.
Is she really saying the object of her affections is going to cause trouble for her? If she thinks that of him, why is she chasing him?
Okay, call her bluff; ask her what evidence she has that suggests he will make trouble for her if she ends the relationship. Ask her to show you the emails or messages where he has blackmailed her that way. If she has nothing to show you, then she is making that threat up, isn't she?
"I can't end it, or I will end up in jail" - seriously, is she eight years old?
As ridiculous as the things she says to try and make you take no action are, the dangerous issue here is how determined she is to keep driving the bus towards the edge of a cliff.
The question is, do you let her, or do you grab the steering wheel and slam your foot on the brake?
I know some of the things I say sound harsh, but none of them are a criticism of you. You should not be in this position, just as the rest of us should never have been in the positions that our wayward spouses put us in.
However, we all found ourselves there anyway. And we had to take action to protect ourselves and our kids. Some of those actions were difficult, some were fought by our wayward spouses, but they had to be done.
And in this case, your wife is now spending money on a jailbird who is clearly keen to exploit her for everything he can get out of her, while she is acting like an infatuated child with no boundaries or common sense.
Mike, he will use her and then throw her away, so blowing this train off the rails is an act to protect her and your children from that.
If it means talking to a lawyer, phoning the prison governor, telling her family that she is spending money on the man that she could be spending on her kids, then so be it.
If your wife thinks she could end up in jail, why does she want to continue this? She is clearly a danger to herself, she is not going to stop, and she needs a sensible adult to step in and prevent her from making what is a bad situation any worse than it already is.
Standing back and letting this run to its disastrous conclusion is not going to serve anybody's best interests, except the jailbird, who can walk away with some cash in his pocket and a big smile on his face about taking a prison officer to the cleaners.
I am sorry to put things so bluntly, but I am only doing so to impress on you the importance of taking some decisive action to halt this process before it gets worse.
