my ex and I broke up in November and in December we started talking again. He says we're dating again but I don't know if he's just using me for sex? He does pay for me if we go out, he'll cook for me sometimes, for Valentine's Day he bought me an Apple Watch (which I had been eyeing), and we hang out or I'll even stay over his house sometimes. We do argue still here and there and he'll tell me he doesn't want to deal with it and I panic and tell him what are you going to break up again, to which he responds no. I just don't want to deal with it. But he doesn't tell me I love you. I don't know if it's because we broke up and we have to build that word up again or I don't know if he's just using me for sex. Help, thanks.
