I’m a little lost, please help.

My niece met her two years’ fiance when she was 39. They dated for two years and moved together there after. At the beginning of their 4th year, she got frustrated and decided to leave the relationship because he wasn’t proposing or talking about any wedding. So, toward the end of that year he went and did the traditional wedding and gave her a ring in front of her parent.

Also, they tried three times to go through IVF but the guy back off each time saying that they were arguing a lot. On their 6th year, he started acting like he was finally ready for the IVF. When they found a doctor and went through all the process, at the time to go for sperm retrieval he started asking if she was really happy with him to want to have kid with him. He’s accusing her for talking about their business to who ever wants to listen to her and that she’s just faking with him to have a baby.

I have been encouraging and advising her to keep calm and pray about it, but I’m so confused and wondering what’s is really going on. I feel sorry for my niece as she’s about to turn 47 Y/O with no kid, no marriage, and no clear direction about her relationship. Please any advice will be appreciated.
