Saying I love you but then ignoring me? 😔😔

Recently I started dating someone. We talk everyday and have done for the last 3 months but it is long distance ( I'm in england he's in Amsterdam) we're not exclusive but he did say I love you early. He visited for 4 days and we were intimate. We were so close to one another and we both didnt want him to leave. When he got home he was said he was sad because I wasnt with him and he had to sleep alone. I told him about how my friends joked about him being my boyfriend and how I correct them that he's not and he said 'Wait- I'm not?' the got sad and said he doesnt know how we're going to navigate this. The day after he was distant all day and ignored me for hours and said a girl came round for advice about her boyfriend. We talked about us and he said he's never liked the idea of a long distance and it'll only get harder to visit when he starts studying next year. I told him i think its too premature to call it a relationship but maybe its too premature to end it too and he immediately said he didnt want to end it so we both agreed to meet up and see how things go. Then the next day he was distant again and I asked him about it and told him it made me feel used. He said that he's sorry I feel that way and its not the case. That his most fondest memories of the trip is being in my arms cuddled up, not sex. I also told him I was worried about something he said the night before. He said ' Do you wanna come over to Amsterdam for one last time or do you not want to?' He told me he didnt know why he phrased it like that and that he meant did I want to visit in general, not for one last time. then he said he had to go suddenly to walk his dog but just played games. He ignored me again then at midnight his time he messaged me and I didnt want to message back immediately because I was drinking with a friend. then a hour later he got upset I didnt reply so I phoned him. He told me he had a rough day with his step family and I couldnt really offer support or anything because I was drunk and he said im just gonna go and drunkenly i said 'are you sure youre ok?' to which he said ' I never said I was ok' annoyed. and I said waitwaitwait...I love you. and he paused for a long time and mumbled love you too but seemed incredibly reluctant to say it.

I know it seems like overthinking but after having the best 4 days ive had in years and feeling as close and feeling the same kinda love I had for my first love and havent had since, I just want to be close to him.
