Don't know what to do anymore!

Hi I have been with my girlfriend 2 and a half years now and we have a kid together I also have a kid from a previous relationship that I see often, since the birth of the youngest my girlfriend just seems to dispise my other child, I have been signed of work since the beginning of the year with a foot injury which means I am unable to pay any maintenance which the previous partner understands but every time I go to buy something which is needed for his school I get accused of still being in love with my ex and not giving two monkeys about my girlfriend now, she just switches at me for no reason it's like she has a split personality but it can be scary, I just feel like I need to leave but I'm too scared to have to leave my little one as I have been through it once before and it killed me, has anyone ever been through this sort of thing before? I have no one else to talk to you I try to ask her why she is like it and it just starts world war 3, thank you for reading

I'm sorry that you're in this juxtaposition :/ I haven't been in this position, but I think that your current girlfriend is acting like this because she is insecure about something. It could really be anything...insecurity isn't logical. I think that if you tell your current girlfriend how you feel and she tries to make you feel bad about yourself then you should really contemplate moving out (at least temporarily). However, this could either have a very good outcome or very bad outcome. On the one hand she could realize that you care about both of your children and her making it difficult for you to support one isn't right. The other outcome is that this exasperates the situation and she intensifies her current feelings. Hope this helps:/

Take her to a psychiatrist / psychologist. After delivery women undergo hormonal changes and some get these mental health problems. Some medications will solve her current mental state and your family will.be happy.

" I have been signed [off] work since the beginning of the year with a foot injury which means I am unable to pay any maintenance which the previous partner understands but every time I go to buy something which is needed for his school I get accused of still being in love with my ex and not giving two monkeys about my girlfriend now" 1. Signed off work since January, i.e. 7/8 months? 2. Are you getting sick pay? What percentage of your usual salary is that? 3. What 'things' for school are we talking about? 4. What proportion of your sick pay goes towards paying your household bills and what, if anything is left over? Or are you paying this indirect and informal form of maintenance *prior* to contributing to the household? See where I'm going with this -ref your 'just switches at me FOR NO REASON'? 5. Given that your ex is the one who claims not to mind bearing with you/the situation, why apparently are you choosing to deprive the person who DOES? '...For no reason', huh?
