I need advice. I have no one else to turn to so I'm posting here WARNING: long post

Some of you may remember my post where I discussed my situation with the biological father (more like sperm donor) of my daughter. I posted before asking whether or not she could sue me for gifts she gave to my daughter and if I had a good case for full custody. Here's a summary of all the drama if you are not familiar with the situation: I am 17 and I just had my daughter a week ago. Me and my 22 yr old ex (sperm donor) broke things off when I was 2 months pregnant. He basically kicked me out of his house because he was "stressed". He would frequently get angry, cuss and throw things over petty shit like not being able to smoke weed for one day of his life or when I'd ask him to go across the street to the store because I was terribly sick and nauseous. I think being with him stressed me out much more especially since I was pregnant. Once I got with my current boyfriend (a month after I left my ex) He treated me so much better. He always made sure I was fed and always wanted to spend time with me (my ex always had friends over or would leave me at his house to go do drugs) After a few days of dating my current boyfriend I had to confess to him that I was pregnant. He was incredibly upset. Not because I was pregnant but rather because he knew that the baby was not biologically his. This broke both of our hearts.. But he got over it and we decided that since my ex wasn't father material he would be my baby's father. Whilst all this was going on my mom and I were talking to my exs mom. She would just give me baby stuff. I planned on letting my ex see my daughter in the beginning but while I got closer and closer to my due date I got extreme anxiety and realized that I could not let my daughter be around a "man" like my ex. He treated me like a piece of meat. He's never had a job. He lives off public housing and disability. He sold drugs. He did drugs (codiene, percocets, acid, weed, etc). And he's in a well known, large gang and does violent things like fighting, shooting and robbing. I feel really stupid for even keeping in touch with his mother but at the time I wasn't familiar with my states laws and thought I had no choice. I assumed she would call CPS or social services when the baby was born because she is very overprotective of her son. My current boyfriend was with me during labor and took off work for a week just to stay with me in the hospital and help out with our daughter. He is the best dad he could possibly be. He is on her birth certificate and he is my daughters daddy. Now ever since I gave birth my exs mom and family members have been threatening me and trying to make me and my mother feel guilty. My exs mom wants to sue me for the baby gifts and for "emotional distress". She called CPS so they could do A paternity test because they don't think my daughter is his. But ironically my latest problem is that she texted my moms phone with a text that reads " Can you send us pictures of the baby (sperm donor) has been asking" I want to tell her off but I don't want her calling social services and making up lies. She is very obsessive and crazy. She will do anything to see my daughter. What should I do? Should I tell her that I do not want to speak to her directly and she may have her lawyer contact me? Should I tell her off? Or should I just ignore the text and hope for the best? Or maybe you have a better option? Please help me out. I have no one to turn to for advice. Also before you comment that I could get him arrested for statutory rape; no I cannot. Colorado has very loose laws unfortunately (i.e. "Romeo and Juliet" law) so our relationship was legal. Below I've included a few pictures I have that depict what kind of a person my sperm donor is. I have about 100 just in case I need proof to file for full custody.
