Advice

My daughters dad lives in Texas I live in Missouri it's a long story as to why we are not living in the same state but I don't want to get into that. My daughter was born in Missouri I've been taking care of her by myself since she's been here she's 15 months, her dad has made every excuse to not come visit her, he thinks it's ok to go 3 to 4 months without seeing her. It's always he doesn't have the money or doesn't have time. But he can travel to different cities to party with his friends, thought it was okay to spend Father's Day in a club with his friends instead of coming to visit her on that day. The last time he's seen her was in May , I've asked him when will he come visit I've even offered to take her to Texas to visit like I've done a few times before, it's always an excuse. Well today he said he wanted to get her for a month in October, I'm seriously not okay with her being away from me that long , really with him not trying to be consistent with being in her life more, he lives with another man I barely know , I'm just not ok with my daughter walking around his house with him having a roommate. He also works so idk what his plans are for where she will be while he's working, i don't want him dropping her off with someone I don't know, he doesn't have family out where he lives so I'm really concerned about who he'd have her around, he's really careless about her safety he always thinks I'm overreacting about that. Idk what to do , I told him I'm ok with a weekend but a month is way too long I'll rather wait until she's much older to be gone that long. What do you guys think?
