Advice please!!!😭

My sons father just turned himself in from old charges and the day before he turned himself in I found out he knew my card number and has been stealing money from me since June about $20 a day ordering beer cigs and food (he's a alcoholic) I never had online banking so I never kept track of my money so I should have watched better(my fault) He hasn't helped me with anything and has no job. I would cry to him how broke I was and little did I know he was going home and calling this store to deliver him 30 packs and cigs. but overall he stole $630 after adding the totals up so I called police and I'm waiting for detective to call me back to press charges he's already getting at least a year and if I press charges he will get at least 1 to 3. But now I'm feeling bad about it because that is my sons father and he does have a problem. Part of me hates him from him doing that and never helped me. he was also cheating on me this whole time I found out after I had baby. Everyone is tellling me I have to and I want to so bad but there's that part of me that just can't deep down. Any advice on what yous would do in this situation?
