So we have gotten to the stage where he ends the skype calls with " love you lots" - well that has happened two days now

I like it but it scares me too. I said it back last night "love you too".
What I am feeling is love, just wish it hadn't been said over a video call, in person would have probably made me feel better about it. But if it needs to be said then when the moment is right I guess it just gets said...
How to explain - Mark was still saying it and texting it even when he didn't FEEL it anymore... that went on for a couple of months (I think).. so the actually words don't mean diddly squat to me... I only want it said when it is fully meant, not a way of saying goodbye at the end of a phone call... I don't want it to be just something that is said because it seems like the right thing to say.
Now I don't think/know if that's how it was last night, probably he meant it fully and it's just me reading too much into everything again.
Am I over reacting, reading something into nothing or am I just being totally protective of myself?
