Should I be concern if he donated money to his ex for her dog’s cremationHe $100?

Whether or not you should be concerned about your partner donating money to their ex for her dog's cremation depends on several factors. Here are a few things to consider:

1. The nature of their relationship: If your partner and their ex still have a close or friendly relationship, it's possible that your partner simply wanted to help out a friend in need. However, if their relationship is strained or hostile, it could be a sign that your partner still has feelings for their ex.

2. The amount of money donated: $100 is a relatively small amount of money, and it's possible that your partner simply didn't think twice about donating it. However, if your partner is struggling financially or if they have a history of being financially irresponsible, it could be a sign that they're not making sound financial decisions.

3. Your partner's communication: If your partner has been open and honest with you about donating the money, it's likely that they don't have anything to hide. However, if they've been secretive or evasive about it, it could be a sign that they're not being fully truthful.

Ultimately, whether or not you should be concerned about your partner donating money to their ex depends on your individual situation. If you're concerned, it's important to talk to your partner about it and express your feelings.
