Struggling in my relationship - I don't know what to do

Recently I've been feeling very down all the time now that I have started college again.

I've had a pretty rough past 2 years. Ive been in abusive relationships and I am broken beyond fixing. My very first relationship was good but there were some flaws, he ignored me and just didn't put any effort, not to mention that he has a big ego. My first bf took advantage of me multiple times, not only was he sexually abusive but he was mentally abusive, he would make me think that I was worthless and that the things that I wanted were not important and that my feelings were wrong all the time. He actually believed that it was my fault that he sexually abused me, and that I could've just told him to stop, but he never listened and that's what he forgot. Through the entire time that I was with him he made me want to kill myself about 5 or more times...he tanked my mental health...I truly hit rock bottom. This relationship lasted a little over 2 years until I broke up with him. I am so glad that I am done with his toxicity. 

About a half year later I started talking to this dude I met on tinder, we were talking for a while and I trusted him right away and he did too. Cut things short, I fell for him quickly and so did he, he actually said I love you first. I was in love with this guy, it had only been a month but it felt like I had known him forever. Anyways about 1.5 months in he suddenly blocks me, no explanation just blocked, I was worried about him and so I texted him on other socials and nothing worked, so I made another account to see what was going on...he was talking to another girl, I actually talked to him with this fake account and got him to confess, then when I revealed myself he would only deny it. I figured out who this girl was and told her the truth, he was furious with me cause he said I ruined his life. A couple days passed by and he apologized and asked me to forgive him, and me with my stupid big heart said yes but only with time. 2 weeks passed and the same girl who he cheated with texted me telling me he was talking to her again and so I confronted him about it, he said he was only apologizing. A few hours later he said that he can't be in a relationship, that he needs time to focus on himself and his career. Well I blocked him so there's that and he hasn't texted since. 

I am now with a man who treats me right. We have been together for about 2 months, we have spent lots of time together, but his new job is very constricting when it comes to texting and calling. He works from 1 to 12 5 days of the week, he took this position so that he didn't have to work Saturdays anymore but now he works longer shifts, so now I can only reach him before he goes to work and maybe 1-2 times during the day for a quick text. It has been difficult cause I would talk to him at like 10 and I would still be awake. But I can't talk with him and I am an overthinker. I know that he's working but in my mind I feel like if he did get a break that he would not use it to send a text to me. I have no doubt in my mind that I love him and that he loves me. He's not the type to joke around, he's one of those people who wants a real relationship cause he's been cheated on in the past and he doesn't want that again. I need a lot of reassurance cause I am broken af. and so now that he's been working and I go back to college I cant seem to concentrate because I miss him so much, and I'm scared that I'm going to lose him. Anyways he's super understanding and like calms me when I'm about to fall apart, I just wish that I had more time with him. We only get Saturday and Sunday for us and I guess I'm greedy cause all I want is more time. Im not really used to having someone who actually treats me right and I just dont wanna lose that. Anyways the constant sadness has gotten better but like its still there from the moment I wake up to the second I fall asleep. I just feel lonely and worthless. I dont know what to do. Anyways I know this was a lot of info but I just wanted to talk about it cause talking makes me feel better...almost like a weight off my chest.
