Husband may be cheating

I’m just honestly looking for support and advice I guess....I’m so heartbroken I don’t know what to do so we haven’t even been married a year we have been together in total over 4 years here lately my husband has been going out so much and now it has advanced to not coming home. I don’t know what it is in his hand but he is disconnected emotionally with everything. I have lost so much being with this man and I’m stuck here with no family but his. I have been debating on leaving and it literally makes me sick to my stomach which makes me more sick as to how attached I am to him. I literally can not sleep when his presence is not in the house. Yesterday we had a talk and I thought we came to a conclusion but he left yet again and didn’t come home he turned his phone off and blocked me so I literally have to block my number in order to contact him. I feel so broken I don’t know what to do I have even went as far as a thought process of ending my life because I have made so many mistakes in my life I just don’t want to do it anymore. I eat but barely I mainly drink and my heart is so so heavy I’m at a lost at my life at marriage at everything.....I’m about to be 30 years old and I have nothing to show for my life....I feel so lost and I have been through so much...the house is in my name but I know he won’t leave quietly I don’t know what to do!? I’m dying inside
