Talking to other girls

I matched with a guy in the year above on tinder 4 months ago. A few weeks went by and we were chatting on the app and snapchat. We then decided to meet up, as he lived in the next county it was a two hour drive for him to get here so he stayed the night. We did a few things but didn't go all the way- baring in mind I have never done anything with a guy. The next day when he had gone he informed me that he had been talking to other girls whilst we had been talking and were at that point were he should stop talking to them. I laughed it off and said nah its allright because I thought I wouldn't care. We have met up 5 times now and went all the way the third time and ever since I asked him about the girls he was talking to and we had abit of banter and joking he asked if I cared and I said no.t But now looking at his snapchat best friends it has made upset to see that the two people underneath me are both girls that he had met online. I know I told him i didn't care but that was then and my feelings have changed towards him. I said that I did't want him to go to uni with me as I would get upset and miss him and end up getting hurt, so basically hinted that I didn't want to me Bf-Gf but deep down I wanted him to ask. hoping that it would somehow work. How do I tell him now that him talking to other girls upsets me, can I even tell him that? we are not BF GF i don't want to be clingy and turn him off me.

You need to know your own mind. He wont know it if you don't tell him. Sit down and think about this relationship with him. Can you handle him living 2 hours away? If you can handle it then you two need to have the talk. Say " I have had some time to get to know you, I have grown to really like you and think that we are compatible. I would like to give us a shot at being bf and gf." If he says "ok" then you start in with the "great, we need to talk about boundaries. I think that since we are going to be exclusive then the messages with other women need to stop now. It was fine while we were just friends but since we are going to be more it needs to stop. Can you do that?" If he cant do that then it wont work out as you are saying right now that it bothers you. If he is ok with it then off you both go on your relationship.
