Im 20M and she is 18F. So Ive been in a serious relationship for about 6 months now. A couple months ago my gf had a guy flirting with her on snapchat. She decided to block him but she still has him on Instagram and he likes all her pictures except the ones with me in. I know I might be overreacting but do you guys think she didnt block him on instagram because she still has some interest??

All i know about him is that they were flirting before we got serious and that she had interest in him.

I personally think its a bit weird that she blocked him on snapchat but not on instagram and its bothering me a bit since I know he clearly let her know he likes her.

Edit: Since some of you ask why Im in a serious relationship at my age is because I didint feel like I was happy or getting anything from sleeping around with different women. Ive slept with 18 girls and I feel like I want something serious. Family is something I really look forward too and its something I really value.
