My boyfriend and I are fighting...

Amanda • Pregnant with my 3rd and mommy to an amazing 10 year old girl and almost 3 year old boy❤️
Please no judgement....
I am currently pregnant with my second child and my boyfriend's 1st. My daughter is now 6 years old, and her father and I do not get along. My boyfriend despises him. Yesterday, I got a phone call from my mother telling me she was going to get my daughter from my ex at 5PM and that I could pick my daughter up from her. I was at work and completely pissed that this arrangement was made when my ex is supposed to meet me halfway and when we spoke last had agreed on 6:30. I live in RI, he lives in CT. On Sunday's, I usually work until 5, run home to let my dog out and take him with me for the ride. Because my ex was so insistent on 5, I left work an hour early, didn't go home to let the dog out and just drove straight to get her at our meeting place. I got there at 4:50, and he didn't show up until 5:45! I was BEYOND angry because he hasn't followed any court orders. He left the state with her without my permission and doesn't pay support. He's basically a sperm donor. He tries to do anything to make his life easier and mine harder and he only sees her twice a month. Anyways, we got into a verbal fight and I told him I'd see him in court and I went on my way. I called my boyfriend to let him know I had gone to get my daughter and was on my way home and he became SO angry with me for not telling him what was going on. I was already stressed about the whole situation and I didn't think my going to get my daughter should be an issue for him. However, now he's telling me that he can't trust me because I didn't tell him what was going on. I was at work when all of this occurred, and where I work I barely had service to text let alone call. I didn't think what I did was wrong! I still don't think I did anything wrong and I feel like he's being unreasonable, especially when he knew I had to get her on Sunday. Do any of you feel I was in the wrong? My boyfriend also said he told me he didn't want me going to get my daughter without him but I don't remember him saying that. If I did, I wouldn't have gone without him. I'm just so upset and I feel like I'm constantly walking on eggshells. We were fighting last night and I was in tears. My daughter was upset as well seeing me so upset. Then he starts in with it again today. I feel like I can't talk to him when it comes to dealing with my asshole ex. I'm so stressed about the whole situation and I've had the WORST headache since waking up this morning. I just don't know what to do....
