dear Robert, I want to thank you for joining this forum, where I have experienced the problem of separation and by having depression, where my then wife had left me on several occasions when our two sons were only young, but as I went to see her and our sons, she returned, but there were circumstances which aren't really related to your post, but I'm sure it was about 3 or 4 times.
You obviously love your two children and this is great, but you have grown away from your wife, and there are for various reasons which you don't have to tell us if you don't want to, the problem is that your wife knows that you get on really well with another lady, so there will be jealousy that now comes into the problem and now she will do everything she can to keep the children from seeing you, as it would be the same the other way around.
An injunction could be as you have depression is that you only see the kids under supervision or for only a certain time, so what you need is to see a lawyer, and if you are on a pension card then legal aid is who you have to see.
What your wife will tell the court is that you are suffering from depression and fears for the safety of the children, so what you need to do is to get a report from your doctor, psychologist and solicitor reporting on your character stating that you won't be any threat.
Please keep in touch with us. Geoff.
