Boyfriend help...

Ashley

So my boyfriend and I have been dating for three months and we see one another every weekend. He seems to always be happy and that he misses me and stuff, but he recently asked if we could experiment with our time together. And at first I thought he meant sexually, but no. He wants to see how long we can go without seeing one another..... my anxiety is already bad as it is due to an abusive ex, so with him wanting to do this has me worried that he’s getting ready to leave me. Any advice?
