Single Dads Support Group

right there with you. I have primary custody of my girls and my wife is about to move in with the OM she chose over me and the girls and is already having his baby even though he is not divorced yet.

I struggle with what to teach them and tell them every day. It isn't easy, and she is currently very short on child support, over $1400 over the last two months. I almost had the power turned off b/c she is shorting us so badly.

I cannot relate with your situation since I share custody with a person for in today's world, I never would have stayed with and/or chosen as my partner to have children with...
That being said, the only encouragement I can offer is, be thankful that you don't have a person who contradicts your actions in raising your child the way you see best for them.
Ways that have helped me when I do have them include;
Staying very ACTIVE as the leader in my house. I lead by example. I practice what I preach to my children and do what I think I should do even when no one is looking...
I've read a ton of material on single parenting, even when married, people have told me "I was the only parent our children have known".
I've enlisted the help of; other parents at my children's school and our church to give me a hand whether it was with driving to activities, etc.
I've learned to include DINNER at every chance we can, in our OWN home. They eat fastfood and out at restaurants at my ex's house.
I SIT with them doing homework, and we play BOARD games instead of watching television or Nintendo...
I know all their friends.
Most of the 'moms' which are my daughter's friends, I feel are threatened of me on occasion because, I'm THE active parent...
I go to school conferences and volunteer at holiday parties at school and am an active member of the PTO for both of my children's schools.
My kids hang out at MY house with their friends more than going to their friends' houses, which they do almost anytime they're with their mother.
Our house is our house, and mom's house is mom's house.

OK, I could go on and on.
I'll say this. Be the BEST parent and don't put pressure on yourself thinking you cannot do it. God gave you the honor to raise your child. Continually pray for the mother and seek forgiveness from your ill thoughts of what happened and then the burden of her not being there.

Children DO grow up faster than you can even think. Take whatever was good from your own childhood and exemplify that. Take the bad and throw it out the window. Take what you wanted and incorporate it into your child's life.
Get yourself a library pass if you don't have one. They have lots of family centric activities. Also, look for meetup groups in your hometown area for single parents/father's etc. There's more of us out there than we realize.
Also, find time for yourself on occasion. It's OK to get a sitter once in a while and go out with some friends or co-workers.
Don't be irresponsible and remember to not forget that you are a parent.
Breathe, it's definitely not as difficult as we think it is.
Just don't try and be the all knowing, all giving super single parent. Get help from friends and family and let people in your life HELP you...
Good luck.

So let them be anti male your a parent and they can just get over it. Keeping plugging at it and just keep your childs best interest at heart like your doing. Be part of their life and show them the way to behave. Toughest job you will ever have but the most rewarding as well God bless and take care of yourself!
