Hello! Thanks for sharing your concerns with us. And its valid you feel bad about your boyfriend being closer the girls. Its understandable why you feel so. Have you talked to him about your concerns and how it makes you feel? If yes, how did it go? Have a great day ahead.

Hey there, hopefully you are doing well. There's a few things I would like to point out;
Hello, Ive been in a relationship with my current boyfriend for 17 months now and recently he went away on holiday. Before this holiday we were as strong as ever but once he came back he told me he had met 2 girls on the holiday and he was going to travel 2 hours to visit them. (This is a major red flag, it communicates he is not showing respect for the relationship. He has a girlfriend and willing to travel to see other two girls instead of using that money to travel with you or make dates with you. He is not behaving like a person with intengrity here) He then proceeded to tell me he wanted space (This tells me he feels smothered in the relationship) but he decided to stay with me. (This means he is keeping you in the background in case it doesn't work with the other girls, and theres a possibility you begged him to stay) He has told me he finds the girls attractive (This a major red flag, if he finds them attractive then obviously he would want something with them) but they are just friends (Sure....) but he never stops talking to them and now has a closer bond to the two of them than we do. (This is another major red flag, he talks more with them than with you, so he is starting to slowly check out of this relationship) Could anyone give me advice please? X (It's up to you, but he is not the right person you would want as a boyfriend. When things are well you will see him behave properly, but when they are not he will start talking to other girls and then traveling to see them. Your self respect and dignity comes first here because he is behaving in a way that communicate he doesn't have integrity)
