Boyfriend doing drugs? felonies, child custody, messed up situation

Definitely not the topic I wanted to post about...but I'm not really sure where else to go or who to talk to yet. I'm 19 and 7 months pregnant with my boyfriends baby. Before our baby was conceived, we were broken up for a span of 2 months, during which he chose to make really shitty decisions. He is accused of 5 felonies...3 for selling pills and 2 for another reason I'm not really completely sure of. He's out on bail and waiting his court date to see if he'll be sent back. I'm not sure if he is completely guilty or not, but I do know that he was apart of the dealing and I do know he was doing drugs while we were broken up. (Pills and weed) The 3 years before we were together, he never did any drugs. And after finding out I was pregnant and us getting back together, he hasn't...or so I've thought.

Keep in mind weed is illegal here. And even if it isn't a big deal to some people, my boyfriend should not be apart of any types of drugs or he will be sent right back to jail in a heartbeat and never get to see his child.

So he is currently using my ipad to text on because he recently broke his phone. So, whenever I go over to his house, I usually get on it..I mean it is mine. Well, last night these messages popped up to his brother.

Keep in mind I have seen messages like this before like "hey you got it?" I've just always assumed his brothers bringing him vape or tobacco or something because he is apart of habits like that. I immediately asked him what it was. The only thing small enough to fit into a dip can would be weed or pills in my opinion. He got mad at me for asking and kept saying "it's nothing" over and over again. We got into a huge fight and I told him that if he was doing drugs he wouldn't be around my daughter because that was the deal from the beginning. He kept telling me it wasn't drugs, but he couldn't tell me what it was🙄 He kept saying "none of your business"

So, after me leaving his house after a huge argument, him verbally abusing me, calling me "bitch, stupid, dumbass", I don't want him anywhere around me or my daughter. this was messages when I got home to him.

I also texted his brother to see what he would say and this is the response I got last night and haven't heard back after my last message.

Like if it was vape juice he would have just told me that....plus I know the vape juice they have wouldn't fit in a tiny ass dip can. And, my boyfriend (probably ex) wanted it hidden, why hide vape juice?

Anyways, yes he is a piece of shit and after last night the things he said and way he treated me is enough for me to keep him away from me and my daughter. But what does everyone think? does it sound like drugs? thanks in advance for feedback and i'm sorry this is so long. also, please try not to judge me. I am good at giving people chances and I really thought he was off the drugs and doing what he could to be a dad like working and saving money. He had been amazing..but i guess not.

PS; he also claims I can't take away custody from him because he has a "10,000$ lawyer" but with his record and my clean record (not even a speeding ticket), what do you think the odds are?
