Want to vent & Need real Advice !!!

Lately I’ve been holding in a lot of emotions that I don’t really feel comfortable explaining to anyone I know.

So , I was in a VERY toxic relationship with my ex of 4 years . After being together for a year I moved in with him and things were okay for the first year but then everything just went sideways. Everything that I never thought would happen did !! So that changed me as a person in the way I live my everyday life . Around March of this year I met this guy and we connected instantly! The day we met I was with my cousin , my brother and my ex at the time. We had pulled into a 7-Eleven and only my brother went in. So I’m in the driver seat and i notice to my left this guy staring at me . I couldn’t really see him well but I just knew he was looking at me but all I could think about was my ex sitting in the backseat noticing what was going on. So my brother came back and we just pulled off . Down the street is where my cousin lives which was where we were headed to. So we get to the neighborhood and we tell my brother and my ex to get out because me and my cousin had to go park the car across the street. As we are walking back in the neighborhood going up the sidewalk this guy is coming down and he stops and say “aren’t you the girl I just seen at 7-Eleven” I acknowledged him but I sort of just kept walking as he was still talking , but then he said something that caught my attention so skip to the point I gave him my number which I know was wrong but I was already very unhappy in the relationship I was in which was already coming to a end besides all the bs I had to go through I honestly was just ready for new attention. So about two days later hung out and clicked instantly. We talked for hoursss from like 6pm until the sun came out 😱😱!! Ever since then we would talk and hang out almost everyday! I loved it I loved hanging out with him and just being around him all the time.

Fast forward to today we’ve been dating for about three months now but it feels like we’ve known eachother for forever ! But we’re still trying to figure eachother out so we tend to argue a bit about literally anything. We both have had bad history with our past relationship so sometimes that gets in the way of how we come together. Some things he does really annoys me because I feel like he doesn’t think things through before he does things . And for some reason that sends me through the roof. I’m a very sensitive person so everything effects me 10x more then it really should 🤷🏽‍♀️. And I let things get to me too easily when it shouldn’t . I don’t mean to catch attitudes over little things but I just have certain expectations that I feel like need to be met in order to keep me sane . And lately almost everything he does has just been getting on my nerves!!!! I’m currently on my period so it’s most likely mood swings but I keep taking them out on him without meaning to . I don’t know what to do because I don’t want to lose him but I don’t want to end up in the same situation twice !! I’m honestly just afraid to fall in love and get crushed again. But he shows me love in a way I’ve never had before ! He shows me how much he cares for me and he puts me before his self !! He’s a real sweat heart with me which everyone finds strange because they say he’s not an affectionate person. His mom loves me and we have been getting closer and closer. So I don’t know what to do because it’s like he says that lately I’ve been distant and have been picking arguments with him and stuff but it’s like I don’t really see it and I don’t know why I’ve been feeling like this . He always tells me that whenever I feel some type of way to tell him right away to never hold back my thoughts. But i find it hard to talk to him for some reason it’s like I’m scared of how he’s going to feel once I tell him something . I don’t know if I’m just like traumatized from my last relationship and I’m taking it out in him or I’m just over reacting or something 😩🤷🏽‍♀️.
