Breaking down!!!

I don’t know where to go to talk about my feelings, so here I am!!! I’m pregnant and I been dealing with depression and anger this go round.(6th pregnancy)...well I haven’t been able to talk to anyone about it because I been feeling very unappreciated by my kids and Bf. I took everyone to the beach for a whole week all expenses on me...I brought my Bf a ring and necklace pure gold and gave him $1000 in cash just to blow on him...(gotten my 2017 refund plus my 2018 months apart) I paid the rent up for 4 months *650 for rent* and paid the bills and made sure I brought everyone clothes shoes etc. even brought EVERYTHING THE BABY WILL NEED plus a little extra lol!! What did I get myself you ask!?!! A maternity dress and jeans I can’t fit. 🤷🏽‍♀️🤦🏽‍♀️ so the Bf needed money for everything coincidentally, (he works 40+ hours a week and even on the weekends he works) I’m a SAHM. I became moneyless and no “thank you” or “no baby treat yourself” or anything!! All I got was complaints and I didn’t spend enough to get them what they wanted or they didn’t want this they wanted something different. So I just been crying in sadness and becoming very angry because no one cared to just ask me “how are you doing” I’m not asking for much I just wanted them to know that I will do anything for my family and I wanted to feel they would do something for me!! But nothing!!! Now that I’m moneyless he ignores me and he pawned the jewelry for money and told me he spent more than I ever do!! Then we got into a fight and yelled out that he thinks this baby isn’t his in front of his kids he had with his ex wife that he treats better than me!! We be together for 6 years and still I feel like I am always doing for him and I get nothing in return. I brought his a car, the latest phones and clothes etc over the past years...he say we’re engaged but never properly proposed...he wants me to pay for the court house wedding Bc he thinks that he shouldn’t have to if I want to get married. But he paid for their wedding and proposed to her in front of her family!! I’m not just about it I’m just drawing out the comparisons and lack of effort he gives me!! What should I do!? Or better yet what would you do in my position!?
