Husbands father suicidal?

So I'm just looking for some insight here because I have no clue what's going on. I've met my husbands father twice in my life. Both while we were dating. We're married now and I'm pregnant with our daughter. He always says he wants to meet me although he already has. He's been on drugs really bad his whole life and left my husbands family when my husband was 6-7 (he beat my husbands mom) so therefore hasn't really been apart of his life. He's been in and out of jail for the past couple of months for dealing meth and caught with weed. The last time he got out he contacted me and apologized for not making it to the wedding and to congratulate us on our baby girl. I was very very appreciative for the apology but told him that I bet his son would love to hear that too. So I gave him my husbands number and they chatted awhile. This was about a month ago. Tonight at about midnight, he texted my husband and asked if we could take care of his dog for a bit. My husband said we couldn't because our apartment doesn't allow pets but he could ask his mom or grandparents to see if they could. His dad was very insistent that the dog needed to be taken care of well. My husband asked if he was going back to jail or something because the dog needed a new home and his dad ignored the question. After that my husband asked again where he was going and his dad said ":( break time". I immediately jumped to the worst conclusion that it meant suicide so I asked my husband if he could be and he said definitely not. But the next text messages were weird. My husband asked what break time meant and his dad responded "you heard me son" my husband asked again and he said "we see eye to eye. One on one" and my husband said What? And his father said "Get back to me on the dog." And then texted again with an old message my husband had sent him and said "I love you son" at the end. I genuinely think the whole conversation sounded off but my husband insists he's high and we do nothing about it. He sounds kind of in denial but I can't do anything because I must respect what my husband says (he knows him better then I do) What do you think?
