Divorce/Custody Help

Hi! In need of legal advice. My ex (29 F) and I (29 M) are currently separated, have been since October of 2022 and are seeking a divorce in the coming months. We do have an 7 month old and we’ve been amicable so that our daughter receives all the love she deserves. Long story short, I found out in August my ex was cheating for months prior from March to August of 2022 because the dude came to our house asking why she wasn’t hanging with him anymore. After taking some time to think and reconsider things, in October that’s when I decided to end things and told her my plans to move out of our old home (it’s her parents home, they own it they just let us live there at a discounted rent price). However, before we had that convo, she informed me she was pregnant. I didn’t know if that baby was for sure mine but I told her if I found out it was, I’d support her and be there for her and my kid. I went ahead with my plans to move out in December of 2022 but while she was pregnant, we remained friends and I supported her and went to doctors appointments, helped buy things, helped her when she wasn’t feeling good, etc.

Our baby was born in June of 2023, so I essentially moved back in the first 3 months and I needed to be there to help her with our kiddo on the daily and to support her more. Then after 3 months in September, we decided Wednesday nights would be a good day to go and stay at my apartment since I still had a lease there until December of 2023 and I was still paying bills there. Now our daughter is 7 months and we are still upholding that Wednesday night agreement. However, there is still no chance of reconciliation between my ex and I but we again agreed to remain friends and cordial for our daughters sake. However, we can’t agree on custody due to my ex not wanting our daughter to be “going back and forth” between homes and she stated to me if I wanted to see her, I’d have to continue to be at our old home a majority of the time, which is unfair to me because I do have a new home I want to be at more. I would like to have 50/50 custody so that way she sees both her parents and our extended families equally. I moved into a townhome and have more than enough room to house her a couple days a week and would even alternate weekends with her and I told her I would stay with her at my parents house (they live about 6 minutes from my new townhome.)

How should I proceed? I am anxious I won’t be able to have my daughter and have our father/daughter time, as well as only being able to really see her when I’m at my ex’s place and I would like to cut back on my time being over there so I can begin to move on with my life as well. I am an educator so I get all the holiday breaks off so when that occurs and she has to work, I am the one who spends time with her on my off days.

Thanks in advance for helping me or pointing me in the right direction!
