My partner and I have been together for over 4 years, we have a 14 month old daughter. I love him but I don't know how much longer this is going to work. Through all the years I've known him he's struggled with his mental health, he gets better and worse, it's very up and down but when he's not doing well it gets really difficult. Lately he's been so sensitive, anything I say can "set him off" and then he wonders why I'm avoiding him. Then yesterday I told him I was taking our daughter to see my mum next weekend, he got upset that I was going without him, it spiralled into him being insisting that meant I didn't love him because I didn't want to around him, honestly I just want some time with my mum and some space to breath for a couple days. He then started suggested he was going to harm himself, he says his a lot without actually doing it, to the point I think he's doing it to get his way. I feel like I'm taking care of him as well as our daughter most the time, I'm always worrying about him and I just can't cope with it anymore but I'm very worried about how he'd react if I broke up with him
