Widowed MIL dating and I watch too much true crime.

So my MIL has been a widow for almost three years. These three years have been hard. I can only imagine what it is like to lose your best friend and husband after decades together.

She recently met a man in a real “meet cute” situation. And she is smitten. Head over heels. She even admitted she may love him on Mother’s Day. They’ve been seeing each other for only three weeks.

I have concerns that this going too fast and she could get hurt beyond a broken heart. He’s been super attentive, sent her gifts for mother’s day. Just showering her with the love and affection she’s been missing these last three years. I’ve been out of the dating game for nearly 20 years, so please help:

Is this love bombing? How do I watch out for signs of exploitation and/or abuse? I am being overly protective because I consume too much true crime? What signs would be concerning in this relationship going forward?

Thank you for any help you can offer.
