Playing words with friends with an ex, weird or not weird?

Yea_I_said_it
Is it normal invite your ex girlfriend to play words with friends with you guys? My boyfriend invited his ex to play words with friends with him like it was nothing...I mean I think it's weird considering they never really talk except every now and then on facebook to say hi. The talking is expanding between them now..and it's weird for me. Shit. Maybe I am just being insecure.

I can see that my boyfriend care about my feelings...If he was more concerned about his ex than me I am sure he would have been honest with me about wanting to add her regardless of what I thought, but he does care about how his actions effect me.
