@intend Set boundaries and do not budge. Don't verbally say them more than once, use actions only. Ignore the calls and texts that are not focused on the child, set time limits and stick to them. Don't allow any flexibility on the time frames you allow. Send 1 text, explain the time at which he can see/speak to the child via a co-parenting app. Give the other parent a 5 min warning and then hang up regardless of what is said to you. Actions always speak louder than words and you must keep self control. Send 1 text at a set interval to explain any changes/advancements/doctor visits/life events. Document everything! Let him hang himself. And most importantly? And it's important that you do this, don't over react or argue. And never respond to any text that isn't directly about the child. You have control. Just breathe. In time, when it is necessary for a custody agreement, if you can prove the other parent is a bad parent, you will keep the upper hand and you want this simply to protect the child. Set boundries and don't budge. It'll take sometime but I think you'll notice 1 of 2 things start to happen. Either the other parents behavior will change in a healthy way or they will disappear. Do not try to make the parent stay around for the child. You are only responsible for yourself. It's up to them to keep their place in the child's life in a healthly way. When you eventually make it to court, following all of these suggestions will cover you. Right now? It's you they are interested in. Not the child.
