OP do you feel that control has been taken away from you? Do you feel powerless?
Someone said, Madame I think, that you may have this notion that you need to please everyone. I urge you to consider this. What have the status of your relationships been so far? Have you gone along with what others have said without question? Have you trusted their judgement better than yours?
You seem to be vulnerable enough to attract the attention of people who have abused your trust and convinced you that nothing is going on. You have trusted that the bruises on your son were nothing but an accident. Your mum sounds like she is the same - thinking that other people must be somehow better than you and know what's best.
If that's the case, you might well be thinking that no matter how hard you fight, they know best and things will happen in spite of you.
This is why counselling is so crucial, to get at the bottom of your character and personality. It's clear to me that you are also the victim here. However social services aren't in the business of giving sympathy.
I do sympathise. Because I think you've never had to fight your corner. You've always accepted what has happened and you've always gone along with what others have said. The biggest thing you ever did was get out of an abusive relationship - that is what you need to hold onto because that was a time when you knew that someone else was in the wrong and you knew you had to take decisive action to protect yourself and your son. It's just a shame that you let your guard down again and put your son in another precarious position.
You need to work on your own issues here too. You need to claw back control and understand that actually, your actions and decisions will make a huge difference to the future outcome. You can't take a half hearted line here and take us up on advice simply to please us. We're not here to be pleased, that's a waste of our time. Anyone can tell if your heart is in it or not and if you are giving out that message on an online forum, just think how easily social services will see through you.
I think you should examine your motives very very closely. Why aren't you fighting more? What's going on in your head? Have you really given up and are just going though the motions for us?
If social services are looking to reduce contact time then you can bet their bottom dollar they are considering adoption or long-term fostering.
I will repeat what I said much earlier on in this thread. We can give you all the advice in the world but we cannot get your son back for you. Only you can do that. It all rests on you now. Don't do this to please us. Only do it if you really do want to become a mother to your son again. This will be a long journey for you and very painful, if you aren't prepared for that then by all means, give up now. But if you think that your little boy is worth all the pain in the world then drag yourself up, give yourself a slap and start banging on a few doors.
