Unwed couple has 4 month old what should we do.

I am the mother (30f) my ex (31m) left my house and moved back to his. We were fighting too much. I was frustrated with his lack of help with the baby. We were not romantically involved for a long time due to the fact he cheated on me a few weeks before finding out I was pregnant . I only moved into my home to help with the baby. He thought having our baby would bring us back together. It hasn't.

I am our daughters primary caregiver. I feed her, bathe her, interact with her, put her down for sleep, read to her, take her to her appointments, I drop her at my parents home before I go to work each morning.

Ideally I know eventually he may get half custody of our daughter.

He has his cousin living with him who has 3 duis. Both smoke weed and drink and heavy cigarette use.

I am not scared of him purposely harming her but I do not believe she would be well cared for if he has her overnights now. Shes only 4 months and he has not been responsible for any of her care. He's never watched her on his own. Hes never driven her in his car because he never gave up chain smoking in his car and has never put car seat in. His family is not active in the baby's life except seeing her maybe once a month.

What should I do? Let him come spend time with her supervised? Let him bring her to his home? To his parents? Let sleepovers?

This hasn't been introduced to the court yet but I'm sure it will. He is doing a lot out of spite because I won't have sex with him and be with him. Only proof I have of that is him texting me how it's hard living with me because it's hard to be around me and not have sex . A few times he started touching my breasts while I was holding the baby trying to seduce me.

The lastest fight was last Thursday and it was the last straw. I was upset he was not helping me in the morning while I was getting ready for work he was outside smoking.

We live in Pennsylvania.

My daughter is my main priority in life, she means everything to me and I have dedicated my life to her. She is healthy, happy, calm, well cared for and so sweet.

What should I do? Let him come spend time with her supervised? Let him bring her to his home? To his parents? Let sleepovers?
