dear Raini, welcome to the forum.
I can't tell you how absolutely sorry I feel for you, so it about losing your job or is it about what your husband is doing, well both actually, but probably leaning towards what your husband is doing.
All the stories that can be made up, such as, she is wanting my help, or she must have text the wrong number, and the list goes on.
My feeling which maybe different to what other people think, is that once trust is broken, there is little chance of any reconciliation.
Others may say that maybe it can be worked out, OK that's their opinion and they re entitled to it, and hopefully they will reply saying so.
Firstly that could be your first thought that it's your fault, but it takes two to tango, so you can't be blamed all by yourself.
He may have his own reasons, which I'm sure he won't tell you precisely, because he will feel embarrassed, but we have to remember that all of us are allowed to talk to someone else of the opposite sex, but when sexual texts are being sent, then he has to face the facts that he has been unfaithful, and really with all of this being done is not being very smart.
If he says there has not being any intimacy, there has to be a logical reason, like work, keeping up with the housework, and looking after your kids, all of which compounds on how you feel, which is totally understandable, so he should give you some leeway and help you all of these routines.
If he wanted to see other women then he should have said to you that 'we have a problem' which we should discuss and face the facts, and then an arrangement be made or a decision to be made.
I'm sorry about your job, but whether or not you feel like finding another one is only to be made on whether you could handle another job. L Geoff. x
