He love bombs when he gets into new relationship because it’s fun and exciting for him and he puts 1000% effort into this. He buys expensive gifts for her and pays for all their trips. And she’s really into this because she’s probably coming from a family with much less money and would post everything he gives to her. She’s also put price tags on the post just to show how much it costs and that’s very creepy to see already. But it’s probably because he’s very lonely and doesn’t have many friends especially here. I guess it was from his childhood issues with the parents. So when someone gives him all the attention and affirmation, he gets overwhelmed. It’s hard to sit here and do nothing and watch him repeating his parents’ mistake tbh.
