If you are doing things that would create a negative environment for your son, you need to split up.If you think that you can get over it and learn to live with each other and produce a happy environment for your son, then stick together.Generally, I think it's preferable to have both parents in the home, but if being together makes both of you miserable your son will pick up on that and that will not be good for anyone.But what you should absolutly not do is break up, get back together, break up, etc. That would only confuse and hurt your child. Clean break or no break. Also, both of you should have custody or very liberal visitation rights of your son.And also, consider this - do you want to be a single parent??
