I know you still love him, but whatever you do, don't do the 'pick me' dance !
He has left you for another woman. Remember that.
When you're weeping into his clothes because you miss the smell of him, he's busy screwing the one with the 'good hair', remember that.
When you want to hear his voice, remember that he's now using that voice to tell the other woman how unreasonable/boring/unattractive/nagging you are, and how lucky he is to have met HER !
When you're worrying about how the hell you're going to pay the bills and keep a roof over your DS's head, he's busy spending all his money on taking her out, treating her to gifts and day trips, showing HER that she's 'worth it', he's very happy to leave you and your DC struggling and broke.
While you're trying to put a brave face on for your DC and to keep things as 'normal' for them as you can, HE'S playing at being carefree and single again, with not a damn care in the world, and you and your DC are the last thing HE'S concerned about.
I know that you still feel 'love' for him, but you need to realize that he DOESN'T feel 'love' for you. If he did, he never would have cheated or put you through this !
YOU and your DC deserve BETTER ! And since you're the ONLY parent who is putting your DC first in all this mess, you MUST get your 'big girl pants' on, and start bloody well protecting both your interests now !
Make an appointment with a solicitor to find out your rights and to start to plan how you and your DC are going to stay in your house and be able to afford to eat, because you don't have the luxury of time. ( And your 'D'H may well be emptying your joint savings/investments etc NOW !
He has dropped a bomb on your lives, but that doesn't mean your life is over, it just means that your new life needs to start today. You need to grieve for the 'life' you thought you had. You need to grieve for the 'love' you thought you had. That will take time, but your priority needs to be how you are going to support yourself and your DC first !
In time, you will be happy again. You will feel strong again.
