I need advice!!! Please!!!

Okay, so my husband and I haven’t been sexually actively for about 2 months and I’m dying!! I’ve never been one who particularly enjoys masterbation. Not because it doesn’t feel good, just because I prefer the real deal. Anyway, we have been to a therapist but he’s just not interested in having sex. I think it’s more of a mental thing than anything but he doesn’t talk about it. I’ve gained weight since we got married but I’m working very hard to get rid of that. (Plus he always says it doesn’t bother him and he loves me anyway) I absolutely do not want to cheat on him because I love him and I respect him, but he doesn’t seem to care that I have needs. When I try and start something he pumps the brakes real quick so nothing ever happens and he doesn’t initiate. This has really started affecting our relationship and I don’t know what to do anymore. What do you suggest?? TIA!!
