Your question was: Why would Match.com Terminate my account ?
I think it's not good to spy on him like that. Be care-free. Just have a good time. ..
I would not read too much into his not logging in for awhile. It may not have had anything to do with you. Even though you have been corresponding and seeing each other for a month, you have not talked about exclusivity so he (and you) is free to see other people. If you are ready to be exclusive, have a talk with him and see if he is on board. If he is not then you have to decide if you want to continue to see him. Either way, you're not sitting around trying to figure out what he is thinking and driving yourself nuts..
Not sure what to tell you. The only way you'll know anything is by his actions towards you. There is an attitude out there that says "dont put all of your eggs in one basket." I dont date using Match.com that way. If I am taking the time to get to know a man then he is the only one who I am getting to know at that time, in that way. But your guy could have the other attitude and want to multidate. You need to find out what is style is in terms of dating...
Oh, "The Talk". I think we all dread this at times. From my own personal experience, I think that it is better if the guy brings this up. This way I know for sure it is truly coming from him and that I haven't pressured him in any way. .
A month isn't all that long to have known someone, so some more time might be appropriate in this situation. since you are not exclusive yet, you are free to date using Match.com others also. I'd date using Match.com around some more. If he brings up why you are doing this, just tell him that he hadn't expressed an interest in an exclusive relationship (thru Match.com) yet, so...and then tell him that you're open to this idea..
Good luck and try not to stress..
