I can’t figure out if my partner is just using me?

I have a partner who is an amazing dad, really helpful round the house cooking, cleaning, does the shopping, we have a good physical connection, get along etc but there are things that really get me thinking. For example our conversations are pretty shallow, he always calls me by my first name instead of ‘babe’, he hasn’t acknowledged our recent baby on Facebook, Valentine’s Day nothing happened. He went overseas recently where his family are and our daughter wanted to meet his family but he didn’t do any video chats with them. When I complained he wouldn’t listen. Twice he asked me to send him $100 since he left. This is after I already supported him for 6 months while he was here and didn’t have a job. Although occasionally he used to bring money home to help with groceries and stuff. It was my birthday recently and he totally forgot and then called me back a little later (I assume after he saw on Facebook) to wish a hb. This whole time I’ve been trying to help him get a visa cos he asks for letters etc. there’s no real romance I’ve tried sexting him but he didn’t say anything just did heart reacts. Is this all normal guy behaviour or is he just using me? Thanks!

Oh, and I also got a call from my uncle saying that he’d messaged him asking for ‘assistance’.. and he knows that that same uncle has quite a bit of money.. 🥴🤨
