Quick life update/kinda venting about my relationship issues?

Hey Ya'll! 

Hope you're doing better then me rn. I had a meh day today but now I think I'm starting to have relationship issues but idk, maybe I'm just overthinking it. Anyways I'm writing about it here because my old irl friend group kicked me out because I was finally happy with someone and they got jealous. Anyways, me and my bf have been dating for about two months now and things have been going pretty smoothly until yesterday/today. Yesterday, he had to cancel plans on me last minute. He kinda ditched me for his friend but I wasn't too upset considering we spend a lot of time together and I understand if he needs space. The second and more concerning thing is what happened today. for some context, me and him have been saying "I love you" too each other for about a month now. Anyways, I was in his car, in my driveway, getting ready to say goodbye. We kissed and hugged per usual, except something was different this time, When I said I love you, he didn't say it back. I know it might not seem like a big deal, but my ex did the same thing before he dumped me. Idk tho, I might just be overthinking. Sorry for rambling lol >_< 

Thanks for listening!!!
