Leaving..

i am coming to 31weeks pregnant and things are not working out with my husband. i decided that i do not want to continue with the relationship anymore, deep in me of course i do want to cause we've been together for 4years and this is our first baby together.. but as i look into how things are and how he treats me after every argument or times when i have my anxiety attacks etc he doesnt seem to care even when i told him about my feelings and what i want. i am in pain every day now because my depression and anxiety attacks are back in life and all i need is attention, xtra love & assurance now that i am in my third trimester but he is not understanding it. there was once i was at my parent's and anxiety attacked me of course they would call my husband but he got mad at me because the call didnt get through and he didnt receive anything from me or my family saying that they lie and all. am i doing the right thing? i have been trying to endure everything since the start of my pregnancy but its the same.
