TW: Self Harm, Long Post, Really Need Advice/Help

Angelica 💝 • Blessed with Twins Aangel💙Aanastasia💗11 Months 👩🏻‍🍼👩🏻‍🍼

So my boyfriend and I have been together for about 2 years and we welcomed twins in May.. we live together as a family... Well, when we met I was going through a divorce and custody battle with my older children etc.. I was truthful and would tell my boyfriend everything and counting on him for support.. in the midst of the whole divorce I ended up losing custody due to my children not wanting to be around my boyfriend because they saw he was controlling and so on.. my boyfriend developed a hatred for them as during the beginning of the relationship as I was going through divorce my children and my ex husband would communicate with me reaching out to setup times days to see, call or video chat with the children... My boyfriend started demanding I stop crying about not having my children with me as I didn't want that life anymore, that marriage etc.. so I should no longer maintain contact with my children on account it made me so depressed and anxious all the time.... I've had these mental illnesses for years prior tho, he knows this! Anyways, my children no longer want anything to do with me as they said I never was able to see them or anything due to my boyfriend... I struggle with missing them and no contact, my boyfriend guilts me everytime I'm sad about missing them and then threatens to tell me well you can go back to them but without our babies!!! 🥺😭 Last night he told me his older daughter from previous relationship reached out to him and sent photos of her self harm scars on her arms!! It triggered me and I began to 😢 he yelled at me and told me to stop it!!! No respect for my feelings as I was a self harmer since my teens and a few years ago got a tattoo to cover up my scars, he goes on to tell me oh yeah I'm sorry I forgot!! Insensitive to my feelings tonight he told me after dinner that he's not telling me anything about his other kids anymore because it's about them and not me and I was only trying to be supportive and offer support, love and care to him as I've been thru that .... He goes on to yell at me it's not about you, it's about ****** you cut for different reasons not the same thing!! I said I'm sorry I was only trying to talk and explain my story and help you overcome this... He shamed me, yelled at me and then said I'm tired of hearing you talk about your other kids!! I said I need someone to vent to and lean on for support as I'm also hurting, he said talk to your providers as in my therapists and doctors!!😭😢💔💔💔💔 then stormed out the house without saying a word to me as I was cleaning up after dinner, he always tells me I'll be back, love you bye, kiss... Not this time as he decided to go hang out with the downstairs neighbor and drink, once again leaving me alone with our 2 babies... I'm glad they're sleeping rn, I'm in so much emotional pain rn... But I can't even cry or I get yelled at for making it all about me!!😭 Was I wrong for offering to help? Is he wrong for telling me he never wants me to talk about my other kids ever again to him?! How am I supposed to pretend they never existed?!?🥺 What did I do wrong?!!??? PLEASE HELP ME MAKE SENSE OF WHAT I DID WRONG 💔‼️ I'm heartbroken and don't feel loved.
