What Could Have Gone Wrong?

I'd really like some advice from everyone regarding my relationship.

 

I'm 24, and I've been with my boyfriend for over 9 years, he is my childhood sweetheart and it was long distance for a while as he went to uni in a different city, so we only saw each other abou...t once a month which was difficult, but we made it work. I trust him and love him very much, and feel that he loves me too. We have spoken about marriage, and plan to get engaged officially as soon as I finish my PHD next year.

The issue is that he is from Nigeria (Igbo), and I'm from St Lucia, I've met his parents who live in Nigeria and his dad was awesome but it felt as though his mum didn't like me very much. I don't know if it was me being paranoid, or if that's just how all mother-in-laws are. I've also been told by my Nigerian friends that people from his tribe don't really marry outsiders. I've asked him before what would happen if his mum didn't like me, and he said all that matters is that he loves me, and his family would need to accept his decision.
However, he's just come back from Nigeria, and he hadn't been in a couple of years, and he's been acting different. He's always been good with communicating, but now it feels like i'm the one making all of the effort, and he starts petty arguments and doesn't really make time to spend time with me like he always did before. I'm afraid that his mum may have poisoned his mind against me, and I just don't know what to do, HELP!

In love with a married man

I fall in love with someone who is married which I knew about from the beginning that he was. But he told me that they going through a divorce, now the wife is calling me and insulting me but I have fellen in love with him already, and the man is telling me not to worry about his wife, and that they gonna sort it out...now I'm scared that he's lying to me and I will be the looser at the end.
What do you guys think, should I give him time to sort things out or do I stop dating him before it's too late?

Not so sure

I'm 26yr old and I'm dating a 41yr old man. The problem is that, the man was married before and had a daughter but the wife passed on (died). I'm only 10yrs older than his daughter. The family doesn't like me but he saw me through school. I'm worried, should I marry him or stop the relationship? We've been dating for close to 7yrs now. Advice me please.
